Here is the response that I received from the tuner.


Yes I was monitoring knock retard. It was only pulling about 1-1.5 degrees, and just for a short burst. I can tell you there's not 50 hp in the tune. There's not that in pretty much any N/A tune.

I will try to upload the file after I zip it ...

Is there any input on the log that I posted? Appreciate your feedback.

Just so you know, I took the stock cats off of my 09 SRT8 Challenger, and it looks as if there are short headers already on the car. I have a picture that I will try to post, but it has four pipes going into a collector.

Did I put the log in correctly, and because I am not even an apprentice to tuning, what are we seeing? It appears that the knock goes crazy a few times, but settles out, as it should, when steady cruising. WOT looks to be the suspect at best, and I do have a catch can on the car. My tuner (if I ...

Did the tuner mention anything about Knock?
Did you have good quality fuel in the tank?
Was this a custom tune done with CMR or the canned tune ...

I went to a tuner, who was recommended by some other dodge hemi locals, to get a custom tune and the numbers are what I ran. I am looking for some insight, not a ass chewing about putting up a post. As for a Newb, to some things, yes, such as tuning, that's what forums are for, to educate. If you ...

Looks sweet! To bad I already got my catch can from BT.

I read the thread in the announcement, and commented there, but thought I might get more attention with an actual post of the concern.

I have an 09 Challenger SRT ...

Well now I am really disappointed in the numbers that I got! I have an 09 SRT-8 Chally w/ M6.

I have a AFE Stage 2 CAI, BT Oil Catch Can, Jet 180 Thermo, Magnaflow High flow cats and competition Catback, I was running the 93 CAI on my Diablo Predator and went to have a tune done.

My first pull ...
