I have tunercats to tune lt stuff with. A datalogger is reall the main issue. That and interfacing a wb is next to impossible
There is a lot left on the table. Also you are very correct under the curve gains and driveability will gain HUGE amounts. I would like to say too peak numbers should increase. I have a 6speed gto here that with a 235/240 cam, CAI and full exhaust did 440whp
I have done a few lsj’s. I dont really advertise since I only do like 1/10 of them as I do the ls stuff. Kinda like the new cobalts as well.
