I like that idea as well.

Brandy16 I see alot of your post, are you also with Diablo like mike and johan? Thanks for the input.

My car is 09 Charger RT 5.7. I am running canned 93 CAI perf tune with 93 Octane gas. Exxon... Curious as to your thoughts on the 91 tune being better? So are you suggesting 91 tune while running 93 gas? I also have catch can and a K&N CAI

Guys, please look at this log and tell me if you see any concern. I datalogged today after filling up with gas just last night. Hoping I got a case of bad gas Ha! P.S. It was 93 Octane gas.

catch can on the way. but would it cause even that much on the stock tune?

Can someone please take a look at these logs. I have had one CMR tuner look at them and he is very concerned. He says knock got up to 15 on the 91 CAI canned tune and my car is even pulling 2-3 degrees timing on stock tune. Something is way wrong. I need help.

Mike did you look at the stock tune log?

Hey Mike, the stock tune is the last tune I uploaded. I did not see any knock when viewing stock tune. I will check it again. What I "hear" sounds to me like knock...kinda like noise you hear when you have bad gas (in the car)....and car runs rough or struggles. Make sense?

Hey guys can you take a look at my datalogs. I am hearing a lot of knock. Yes its mostly at WOT but not alway, sometimes I hear it and feel it when rolling around 30-40 mph then hit the gas to speed up or pass.

My Car: 2009 R/T K&N cold air, suitcase muffler delete. Tune= 91 Oct CAI Performance ...
