I see a lot of post on other forums stating that an email tune is better than a can tune from DS even for a stock SRT8 (CAI,exhaust, catch can)

Is this true?

If you had to ask you need to do some more homework to understand what a tune does and what you mean (or will mean) by "better"?

It doesn't have much to do with "better". DS supplies tunes for stock/slightly modified (CAI and cat back) cars. They're as good as you can get. If you want to go more aggressive, less aggressive, more torque management, less torque management, torque management at different places, tweaked for different fuel, yada, yada, yada then you go with a custom tune and tell your tuner exactly what you want. All that has to do with preference, not "better". If you don't understand you might get a custom tune and like it better because the tuner you got it from sets his tunes this way or that way. On the other hand you may prefer the DS tunes over the custom tune you got for the same reasons.

The DS tunes are for stock or CAI/cat back cars. There just isn't much variation between one to the next. They supply their tune for that/those cars. Once you get into headers and especially cams/heads or further mods then there are a million combinations and variables and DS isn't in the business of doing one-off custom tunes for specific setups. You go to a custom tuner for that.

Would you care to ask your question again?

I am trying to find out what makes a email tune better, check out any srt8 forum and you will see guys post that email tunes perform better than can tunes.

I can see it if you had a cam, long tubes...etc but for a stock srt8 how much more can you improve on the timing and A/F ...I figure that if you fine tune your a/f and timing you might get another 8-10rwhp (which is hard to feel)

they also mention that shifting is better...why? I would figure DS would of reduced our TQ managemnt as much as possible.

Sure... ask them why. Their tuner should have told them, and they should have asked. "Just how is your tune different/better than the canned tune?" A good tuner will tell you that, for a basically stock car, they can make little changes here and there to suit your preference but the difference from the canned tunes is not going to be worth the cost.

You could probably fine tune it to improve *for your particular gas and conditions* but I seriously doubt if you could get anything near 8-10rwhp by doing so. The DS tunes assume very good gas and don't allow for the oil through the PCV if you don't have a catch can. So you might see knock retard with less than that. But the PCM handles that. So you might adjust to eliminate the knock retard and maybe gain 1 or 2rwhp? You can do that with the handheld.

they also mention that shifting is better...why? I would figure DS would of reduced our TQ managemnt as much as possible.

I think if you reduced TQ management as much as possible (so it still shifted most of the time) then you would start breaking things prematurely. There are other tradeoffs. Lot of people want their shifts to feel like you got hit in the ass with a giant sledge hammer. That may not be the best thing in the mid/long term. Lot of other people are asking for more torque management. So again, I think when you say "better" you are actually talking about preference. DS is going to include a single tune that's going to be "best" (what they think will be preferred by the most people). And they have a single tune for 4 configurations. Octane 1 w/wo CAI&exhaust, Octane 2 w/wo CAI&exhaust.

great explanation Quick....

great answer....thanks for both of your time.

The canned tunes are very conservative, so email CMRs can definetly make a difference. HOWEVER, all are not created equal, and I have heard quite a few horror stories. For instance, DCX Depots tunes are super lean, and tend to cause problems. MHPs tunes feel great, but have quite a bit of KR, and very little actual power gains. Actually that seems to be the norm. The Email CMRs are more "feel" tunes. They may feel better, but theres no real power gained from them.

Can you show me someone complaining about our tunes (DCX Depot) being lean and more importantly instances of our mail order tunes causing problems? I would hope you have some concrete examples of this to make such a bold statement. I'm sure if you look hard enough you will find issues people have had on built up combos with possibly a dyno tune that didn't provide the proper results. As with any large build/heavily modified car there are always more opportunities for issues to arise.

But in this particular case we are discussing mail order tunes in which we do not normally do forced induction or extremely custom setups. So I would like to see where our mail order tunes have caused "problems".


To answer the original question, we provide 3 datalogging sessions to dial in the VE table for your specific combo. This process GREATLY improves drivablity and feel for the car. Even if it doesn't add a single HP, people have been extremely happy with the feel of the car after using our service. Here are some of the reviews:

Also the canned tunes from Diablo are good but obviously for the most gain with your tune head to a dyno but also you can datalog and get a vendor to send you a tune via e-mail. I went with DCX depot and they sent me a great tune that added more HP.

Best of Luck,
James

The DCX tune is a must. Ask for Tim.

Comparatively between the 93 and the DCX, I ran consistently .15 - .2 tenths faster in the quarter mile on my RT DCX did me right (also reference Dodgetony as he has had some of the best 1/4mi track times in the RT and also pulled 2 tenths faster in the 1/4mi). Talk to Tim at DCX (http://www.dcxdepot.com/contact_us.php) and he'll help you out.

Just installed DCX Depot's custom tune and all I an say is Awesome!!! What a difference (over all).

I haven't been able to really open it up to get 1/8th or 1/4 mile times but I have been able to tear-up the local streets to post some 0 to 60 numbers.

Stock: 5.4 sec to 5.6 sec (repeatedly)
All mods including the Predator (CAI 91 octane): Best was a 4.87 sec
Added DCX Custom Tune: 4.72 (first run which was all I could do last night)

I need to take it to the track because I am getting alot of wheel spin during all the runs....not good for time results but oh...so much FUN!!!!

Big thanks to Tim Combs

Guys I can say that the tune they gave me added 13 HP and 18 ft/lb of torques

BUT the throttle response it added was the Kicker it was, I think that right there made it worth the money.

these guys are great to work with.

I got mine yesterday and now I am getting rubber for about 20 feet in second gear......nice!

Thanks,

Their tune was the best mod I have done to my SRT 6 speed. It made the most difference out of all the things I have changed so far. I highly recommend it!!

HighPrime
I can say, without any hesitation, that the DCX tune has made a difference for me. Car no longer struggles for air above 4K, and I can feel the car pulling harder all the way up to 5.5K.

Thank you Tim and DCX you guys ROCK!!!!

I installed mine today and I love it. Feels like the Jeep lost 500lbs.
The DCX tune is way better, it seems to rev out faster and just feels alot looser all around in a good way. Launching is nuts, the pavment is cold here about 17* F outside. If there is anything on the ground at all my Jeep will do 4x4 burnouts through first gear w/ TC off

Just got done installing my custom tune from DCX and I must say....WOW. Tim and his guys did a great job. Quick response, better shifts, overall a great upgrade.


Mcopare
I love DCX.....great tune! can't wait to get my headers and cam tune on my 2010!!!

I'm sure I could simply by doing a search on CherokeeSRT8.com, as thats where I used to spend alot of time and got most of my info. But I rarely go there anymore, so I'm not going to.

I left DCXDepot with a brand new N/A 426 that destroyed itself in less than 7000 miles. My knock sensors were TURNED OFF below 212 degrees F, someone took a rat-tail file to my crankshaft gear to try to make it fit the K-1 crank radius which put my oil pump in a bind which in turn wiped out my main and rod bearings because of the metal being shaved off of my oil pump gears.
I'll send you the tune, crank gear, bearings or any one of my SMOKED pistons for you to examine...can you say "four corner scuffing?" #1 piston had a broken ring land!
Heck, when they closed up shop and handed me my keys for my 24 hours drive home, my idle was set to something like 1700 RPM and my fans ran constantly.
Ask Tim. He knows.

As far as I am concerned, DCXDepot failed...at least in my assembly and dyno tune.

Well, theres another one for you. And my friend Chris tells me that he knows who said the DCX tunes were lean and not very good. I'm not gonna say who to avoid causing a problem, but lets just say he's among the very best at tuning the Hemis, trailing perhaps only Johan (or maybe not even).

No not really. We are discussing email tunes. That is not what he is talking about. KingSavage definitely had issues, and not sure that needs to be discussed here because it's way more involved than the question at hand.

The question was about email tunes.

So let's get this straight, your information about our mail order tunes is coming from another tuner who is competing with us most likely? Doesn't really sound like a really good source of unbiased information. I'd like to hear this from an actual customer and not someone who needs to spread false rumors about their competitors to gain business.

I encourage you to search the Jeep forums, we have many many happy customers on the Jeep forums.

With as many customers as we have, you might be able to find one or two unhappy customers but I will guarantee you will find an overwhelming positive response.
