Re: Hitting a wall at 4500rpm [SOLVED]

Yea... looking back that was a little boneheaded on my end. Part of what through me off was the example tune that I downloaded with the NEMU software (very similar setup to what i was running... 550s, speed density... etc) It was pretty retarded across the entire map compared to what it should be. I...

Thanks again for everyone's help.

Re: Hitting a wall at 4500rpm

Haha... that was not a typo, unfortunately. I guess when I read to pull 1deg per psi, i assumed that was off of base timing of 20deg. So, yes, I’m running a final ign value of 15deg at 5psi (5deg retarded off of base idle of 20). Sounds like I may have a significant timing issue. I’ll dig into that ...
