lb7 tuning
hi, i am trying to tune a buddies lb7 and i cant get any progress. like i did on my lbz, i modified the throttle based injection quantity table, the timing tables, base torque, and bumped the fuel pressure a little. i flashed the tun onto the pcm and didnt change anything. im looking for about 80 more rwhp. does anyone know what im doin wrong?
check the MAF limit tables.
What year is it
