Low Power, Lean, stalling after driving 1400 miles on new turbo build.
Hello all,
I have a 1992 prelude Si with a budget turbo build rigged up to the stock motor, its running the gated boost which i think is 7psi but i'm not sure, the MAP never goes beyond column 10 on hondata. I have been dialing in the tune and drove to chicago and back successfully. However when i got there, while idling the car did this sharp hesitation thing which felt like a misfire, but the rpm didnt drop. Now that i'm back the vehicle stalled in motion after a 20 minute highway drive where it ran super lean the whole time. It crank no started while it was still hot, but when i got it back to my house it started right up, still running pretty crap. Any clue whats going on? I have no CELs and i'm worried i've blown the engine. haven't checked compression yet, will tomorrow.
