Tune Review? Not happy with current tune
Tune Review? Not happy with current tune So i just put in my lq4 l92 motor
I know i just got a rough tune emailed to me from my tuner, but it worries me that he said he was unsure how to scale the ls3 injectors, if ls3 maf was diff, among other things. That there scared me that i might not be going to the right guy
truck is running lean and is misfiring some. I know i need to log and get it on a dyno to get it good, but im still worried its not going to be peak with who i have.
Didnt know if anyone could review the tune file i have, efi .ctz file and tell me if it is ok for a rough mail tune, or is like way off.

l92 heads milled .015 .040 gasket

with a setup like that your best bet is to find a local competent tuner.... if yours wasnt sure how to setup ls3 injectors, thats a huge red flag. they are stock gm injectors and tune very easily. Go to hptuners forum and find Dstek's ls3 converted data. The ls3 data in raw form cannot be used in an ls1 pcm as its the wrong format. Dstek converted it for us. Using his tables in the tune he posted just copy them to your ls1 tune and you'll be good to go.
