Oh I'm not taking his side by any means, but he's fairly reputable and apparently didn't think highly of my email tune. Since then, I was sent a new tune and it logs great like the previous tune did, but with a little less fuel. It should make the power the 91 CAI tune did (a 6 horse difference). I ...

I just went outside and installed the 93 Octane tune, no CAI. I run 93 anyway, so why not? As I recall, I had a bit of knock with the 93 tune, but the car hauled ass. I'll run it for a bit and see how it goes. I didn't have a catch can before either so maybe that will calm the slight knock I had ...

Good, not great.

Car has a drop-in K&N filter in a Daytona airbox and a DiabloSport Predator tune (various, see below). About 35k miles and not much else.

Pass 1: Custom email tune: 297.77 hp, 335.14 tq and pig rich (11.49)
Pass 2: 91Octane CAI tune: 303 ...

Exactly. Pass on the ACES crap regardless of what you see in the other forums. It's pure snake oil like any additive usually is and won't help anything other than to lighten your wallet. Take that money and pay Johan to do an email tune for you. He's a class act and will work with you to get a good ...

How do I add fuel in the upper RPM ranges? Say 2-3%?

I typically use Sunoco 91 Octane gas. It's the closest and most convenient. Based on this log, should I be adding fuel in a certain range? What about timing?

This morning I installed a catch can and decided to do some data logging (attached). I'm getting some ST knock (4 degrees) and LT as well (2 degree) when I punch it on the highway and I'm at speeds of over 100. I got the car up to 120 and the knock settles down.

Any suggestions?

Has this always been the case? I recall people sharing tunes on here often.

I'm about ready to break out of the winter de-tune on my '08 Charger R/T and I'm hoping somebody out there has a great tune they can share with me.

The specs: 5.7 V8, K&N drop-in, annnnd that's it (for now).

I was hoping somebody would have a tune that would perfect timing, shifting, throttle ...

I agree with the OP about the factory intakes and have been arguing against cold air intakes for a while. Most factory setups flow air just fine, and just about every one of them is a sealed pathway to some place outside of the engine bay. Most so-called "cold air" units have you throw a filter at ...

I've heard and witnessed otherwise. I ran the stock 91 tune and had some knock. Called around to some of the people who sell the Predator, and they told me to try the 91 CAI tune and log for ST knock. They were right, knock was reduced.

5% here since DS builds in 15% already into most of the tunes. 20% total.

How long, exactly? 30 seconds? Does this wipe the car's computer and reset defaults?

Seriously? :roll:

Numbers, please. One tank on a stock tune to a tank on the MPG tune. I did it and lost about 1.5 MPG with the same gas, same driving style. 1 MPG isn't something to really market anyway since most cars swing higher or ...

The MPG Booster tune doesn't work for me . In fact, it made it worse in my '08 Charger RT. They need to tweak it. fixed...

Problem is, Mike, it doesn't work for most people. Now the other tunes are great, so I'm not bashing your product. But the MPG tune just doesn't work in the LX cars though. I ...
