Well I changed my fuel yesterday after reading your responses to 5, 8, 8 and then drove it around to get it up to temps and did some more datalogging... The only KR I had was some brief ST right after shifts and a couple of tiimes a very brief spike (literally looked like a spike up then down) when ...

Never did log the stock tune... guess the thought never occurred to me since I wasn't planning on running it except when I have to take it to the dealer...

Okay... I guess that would involve asking everyone I can what their recommendations are as to who to use, and who to avoid to make sure I find someone who can do it right and resolve my tuning issues.
Suggestiions? What to look for? Pros? Cons?

Thanks for the response Quick...

The 10.8-11.2 AFR was at the tailpipe. I have just ordered a Wideband AFR gauge to install the proper way but don't have it yet.
The readings were while strapped to a dyno. Not going however on just the AFR reading they got, the HP started out at 354 with those ...

Thanks for the help MagnumSRT8.

Yeah, ive seen that the 5.7L doesnt get much knock. The Srt's on the other hand have a ton of knock. I found most of my knock to be false knock when we did the CMR tune. Just a noisy engine. Nothing wrong with the engines but they are noisy. We had to desensitize the sensors a bit. DID NOT TURN ...

I see Diablo responding to numerous threads on this forum and other forums.
But when it comes to solving KR and basic tuning, Diablo seems to be fairly quit.
Maybe this is because they do not want to share their approach to tuning to keep their proprietary methods from the competitors.

There ...

That's some serious knock. First try a different gas station and add a healthy dose of fuel in modify parameters. The difference in the CAI tune and the non-CAI tune is more fuel in the CAI tune. Go into Modify Parameters and try adding 6%, 10%, 10% (that's low rpm range, mid rpm range, top rpm ...

Well I added a bottle to my tank earlier today to make sure I didn't have some bad gas giving me the KR I am getting and saw no change in kr... guess that means it isn't my fuel. I took away 1 degree of timing across the board and all LT KR was eliminated however... Still getting ST KR as high as 5 ...

Just because you see the same company name on the gas truck that fills the ground tanks at your favorite gas station doesn't necessarily mean that is the actual brand of gasoline you are getting at the pump. I used to work for the corporate office of a well known brand of gas a few years back and ...

I was runing similar fuel adds on my 07 Charger SRT8 using the 93 CAI tune and when I had it on a dyno last week it showed the AF ratio as being around 10.9 to 11.1 which was so rich it had to be costing me hp. I reduced the fuel to get the AF where it should be and ended up with +5, 0 , 0 on fuel ...
