Car sputtering at full WOT
When I get into boost my car loads up and backfires/sputters. Car is tuned by 51/50 racing in Santa Ana with Evo 9 turbo 1120 doc injectors muse 02 dump full exhaust intake intercooler piping etc... Just the normal bolt ons. Just can't get into boost really . The codes it's throwing are P0113 intake air temperature sensor 1 circuit high, p0102 mass or volume air flow a circuit low, and p0107 manifold absolute pressure/barometric pressure circuit low. Anyone that could point me in the right direction please help!!

May be a long shot but look at the ceramic part of your spark plugs. When I pulled my head off to do head studs the spark plugs magically decided to crack on the porcelain part. Took me a day to figure out it why the hell the car was fine under normal driving, but under 16+ PSI of boost it just sputters like hell.

It would have to do with your maf or map sensor. Also check your spark plugs, make sure you're using ngk ones or better. Not some random plugs bought from autozone or something.

So two things my mechanic found with the car that may have caused my sputtering at WOT.
Boost leak on the jpipe. Nipple blew off
Spark plugs gapped wrong. I have since bought a feeler gauge. I was using the stupid coin type gauge.
I haven't really tried getting on it as it is now my daily for a few months and don't want any issues to arise. I have "tested" it without any issues. So I believe my issues were resolved.
