Finally got my car back, and I'm 80% sure the TPS is shot (as is the guy that built my car) however I want to confirm my thoughts with your opinions before I splurge and drop another 250 bucks I don't have.

This is on a fresh rebuild with new injectors, afm, and plugs.

Issues are as follows:
- Car runs fine under full/partial throttle as long as I run in vacuum. Once I go into positive vacuum/boost it runs too choppy and doesnt accelerate (seems like its flooding)
- Car idles at 1500, but there is a pretty massive streetport on the engine. However sometimes you'll hear the brppp-brppp-brpppp sound from the exhaust followed by a prolonged brppppppppppppppppp sound. Hmmmmm
- Car is getting around 6 MPG.

Temps and pressure look fine on the car.

have you tested the TPS or adjusted it? or are you just shotgunning the problem till its fixed?

Is it back firing when you get into boost? Sounds like limp mode to me. See what codes if any the car is throwing and start from there.
