Sorry Mark for lack of specifics. I personally didn't do a before and after dyno, but from what I recall from others, the hp/ torque gains were not significant and varied. The improvement was with the A/F ratios. Again, from memory: with the P&P, LTH and Catbacks there was some indication that the cars were running towards the lean side, but not dangerously so. The B&G put the ratios in "safer territory". Again, I know this is a non-specific answer. I believe the dynos were found on the LX forum around the time that the B&G was first making noise. For what it's worth, it's a great mod.
