[Camarocore]

Hello,

08 GT with Stage 2 kit with Boost a pump. (Auto)
After Headers install the car ran fine for few and then
its start to be lean (WB) and doesn't go into boost and the tranny start to slip also the FuelP doesn't go higher then 42PSi.

Not sure if it is a O2 sensor issue? Reading lean and going into limp mode? Someone with real tuning expeience may know more?

Who tuned the car?

you will have to add O2 sensor delay due to the new O2 sensor location on the headers. DUN

stage 2 ? centrifugal or roots blower ?

if its procharger with blow thru MAF sounds like there is a leak after the MAF which would explain why its lean and why you are not seeing any boost
