I have a 2006 Chevy Truck here with a 5.3 and a Procharger. I'm new to GM tuning but I've been tuning for about 6 years. I have my own dyno/shop and tune 2-4 cars a day. But this GM stuff is kicking my ass. I've done 2 08 Vettes without issues, but not sure how to deal with the blower on this one.
Truck is OS 12587811
What is the best route to take to tune this? I noticed there is no custom OS available for it. I tried to see if I could rig the tune for now until a custom OS becomes availabe. I was somewhat successful at getting getting some WOT tuning do to get some power numbers but otherwise I'm lost. Is there anyway to tune this thing without a custom OS?
I put 44lb injectors in it, changed the values for that. I've been able to get it to drive ok on the dyno and when I got WOT above 4,000 RPM it's good. But on transition, it goes super rich (because of the bs tweaking I had to do to the VE table). Basically if you go WOT below 4,000 RPM it's so rich won't gain RPM. Please help! It sucks to feel so lost.
Made 345 rwhp so far.
