Could I copy all injector data from ls1 stock file to my tune? I bored my 5.3 lm7 to 5.7 ls1 specs because of pitting and used the ls1 flat top pistons. The Tahoe is originally flex fuel and has 33lb injectors. I believe the ls1 used 28lb injectors. The tune is running ok but it is leaning out with load (going uphill) and causing some knock. I also see either rich or lean spikes on deceleration. I've noticed high MAP 60-80kpa and Cylinder airmass 40-60g and o2 1 and 2 lean trims during the knock events. I'm new to tuning but feel like maybe the stock injector settings are causing this. It is running fine and the knock isn't too bad but bothersome. I haven't floored it and also on revision 85 due to the knock. lol.
This is my daily. I'm trying to build it pretty mild.
