I'm in the process of tuning my turboed zc with chrome and for some reason at 5psi it whants to go instantly lean. I can partial throttle it to red line and have plenty of fuel as long as I keep it lower that 5 lbs.
Info:cut is set at 7800 rpm (built head) and launch control at 4200. I'm running rc 750s and a walbo 255. Gm 3 bar that worked in last setup.
I'm gonna try a different map sensor but if that doesn't work, other ideas would be appreciated.

u should prolly post that kind of question in there im sure u can get a lot more help from those guys than most guys in here. only thing i can think of is maybe the wideband u are using may not be hooked up correctly or may be broken already. i do know that some of the widebands will work like a light show if not hooked up correctly

 

Do you have the GM 3bar promagrammed into your current ROM?
*edit* it sounds like its doing a cut a 5psi obviously, go to setting and option and see what the boost limit is.

 

widband is working. I know its leaning out because no matter how much fuel I add it acts like its hitting boost cut. also, the boost cut is set at 22lbs.
