Correct injector data. Mine ran lean until I corrected the injector data and it felt weaker than stock because of it. I used injector data from a 2008 Express 4.3L factory tune I downloaded off the HP Tuners repository to correct my tune. Flow rates, minimum pulsewidth, injector offset, etc is all different. 2008 4.3L had the upgrade spider from GM and thus the tune had all the correct values to paste into my existing tune.What kind of tuning?

Found it, knew I posted it somewhere. This was data I pulled out of a 2010 tune for that thread, but the data itself is the same as the 2008 tune I used years ago.Do you happen to know if those are posted anywhere on GMT400?
