if there was anything else i can see or hear to give me a clue, but i didnt find anything. Took it for a quick run, through 1st and 2nd boosted up perfect felt fine for 2 little bursts. Then on the third time it backfired again close to 10psi in 2nd. Did one more burst in 1st and it backfired early like 5psi or something.
Now im thinking its definitely not a turbo, maybe nothing serious, something electrical maybe? Any pointers would be great.
