I pretty sure this should be posted somewhere else but I don't know where the stickied thread is for L99's. But here goes I dynoed my car along with my 2 friends yesterday a E90 M3 and a C6 Z06 I have a 2SS LS3. All cars are stock and was one on a Mustang Dyno it was a fourth gear power pull. The M3 went first and dynoed as expected 335 rwhp average which is about right since he has 414 to the crank. I went next and the first pull 414 rwhp then the tech was like its suppose to be 426 to the crank right I said yes so he pulled it again. The second pull was 428 and the third was 429 rwhp weird. The tech said "you have a very strong motor and I need a tune AFR is off". The Z06 went next and he dynoed an average 495 rwhp again weird because he has 505hp to the crank. We then put the M3 back on and he dynoed 335 rwhp. Here is the the 2 print out the tech gave me. What do you guys think
