Put stock BPV back on,....still backfires.....

[stevessvt]

So I put the stock BPV on, reset the ecu, but it still backfires in between shifts when driving it hard. I do have a second cat race pipe on,....could this be the reason? It has almost 300 miles since ecu reset,.....could be still learning stft/ltft?

Also,...its been raining for 4 days here and I noticed my idle vacuum is about 1/2 psi lower than it used to be. It was about -21.xx now about 20.3-.6. Does weather affect vacuum?


Thanks

Thanks

it could still be learning, and yes, weather can effect vacuum

Have you removed your resonators?

Check all your clamps to ensure they are tight. 4 on the tubes of the TMIC and the one on the turbo inlet coming from the intake.
