mikel, thanks for the reply. When I get home obviously I will go back to the tool and double check the tune names, and re-flash. My suggestions still stand on modifying the installation screens to be consistent with our equipment.

As for the other pokes at my mechanical capabilities and age along ...

I installed the 87 tune without any problems. It's a little weird to go through the key cycles and the vehicle doesn't shut off while the tune is loading. Also the "no buS" on the display is curious. As a note, maybe DS should consider doing a quick video to show people what to expect. The throttle ...

Really! I have been using it on a Tahoe since October and was thinking "no way"! How it pays to come back to the forum and browse around! I will try it when the weather warms up a little around here.

By the way guys thanks for getting the Jeep GC tunes done. I will be ordering one for our GC in the ...

It's the gas, buy better gas. Any LT knock is bad, eliminate it or your car's performance will suffer. The computer is pulling timing all of the time if you have LT knock.

^^^ TRUE "the proof is when the rubber meets the road" When he gets some acceleration times he can prove if the dyno is accurate on both the base and modified numbers.

All good calc's shown above. Given the 85% efficiency those seem like reasonable numbers. There is no need to guess at the ...

I tried the tune with our GC. It seemed to get about the same MPG as always 17-19 (highway), but you are able to use regular gas with that tune. Throttle response was pretty good, but if you put your foot into it, you can tell the performance is dialed down. Works good on highway trips where you ...

I am curious, is it quicker with the DS tune or not?

Now go out and run some 1/4 miles and see what it really does. Sounds like a good tune.

Yea, you really need to be careful adding timing into a 93 oct tune. You need to log like we talked about before and check that ST and LT knock out or it may be running like an ape with a broken leg soon. Or go pick-up a new 6.4L Chally or SRT8

Prohunter, did you do what I told you in this thread? http://www.diablosport.com/index.php?na ... ic&t=28944

I was able to look at it. I thought it was a V6, because I know either one of the Hemi's cannot advance the timing that far at WOT. But, dude it looks fine. All of your WOT blasts are without ST Knock retard except for that one spike. Your timing advances smoothly, your RPM climb smooth, looks good ...

What engine is this?

It seems ok, hard to tell, but you need to go out and plant your foot on the floor and log at WOT from stop to at least into 3rd (at a very safe closed road of course). Your log indicates your throttle is only at 88% throttle and your max RPM never got to redline.

^^ nice work. What was your 60' time?

Oldschool if you are changing the 93 octane tune, you may want to just try the 91 octane tune. You may be surprised. That may work fine as is.
