Turbo tune
I'm working on tuning my rear mount turbo kit and I keep having driveability issues. Till about 3000rpm the car is lean. If I cruise at 50 under part throttle it just bucks and jumps. Once I get under boost the tune is fine. I have an FJO wideband hooked up for viewing. The idle is way lean as well. Since you can't unhook the maf for tuning do I just work on the maf table? Anyone with ideas? Any help is appreciated. This is a 99 camaro, auto with a stock long block.
