My car is running lean as boost builds and then runs rich as it stops at 20 the settings that came with stage 4 are for race gas and 24lbs anyone have a good setup for 93 and 19-20 lbs of boost thanks

 

Well you need to get yourself a Wideband of some sort and tune it out to 11.1-.5 for a safe and conservative setup. Ppl can give ya setting but all cars are different, I would opt for a wideband just for the safety factor. If I where you I would decrease all the setting atleast by 10 from 3500-7800 and keep the boost at 19-20.
