Hey Greg.....after reading your list of mods under your signature......I realized that you have the LS1 MAFT , 13g turbos and 550cc. injectors. My question is: did you ever do the Fuel pump re-wire to get more volts?? Also what are your S-AFC settings at? and if you have an EGT gauge are you leaning out when WOT (I'm assuming yes)?? Also what boost are you running??

Just to give you an idea, here's my set up:

LS6 MAFT, 357 turbos and 550cc. injectors and fuel pump re-wire. Before my fuel pump re-wire, I was encountering the same problems you were having; I had started out with lean settings then had to richen as the rpm's got higher to avoid my EGT's from running real hot. After the fuel pump re-wire mod my Egts dropped and I was able to lean out my S-AFC even more consistently toward the higher rpm band and it was more consistent throughout the Lo and HI throttle spectrum of settings ( I recall having everything set at
-33 across the rpm band consistently and the car ran Strong!!). Then I finally got around to getting the LS6 MAFT which provided me with more airflow with the 357's; Now, my S-AFC settings are right at 0 across the board for LO and HI settings on the S-AFC and I'm good with no knock on the datalogger with pump gas @15psi and no knock with race gas @ 24psi !!!

Hope that helps and gives you some ideas.

I'm itching for a Chicagoland gathering............just need my work to ease up....

okay......need sleep.........

good luck.
