I have a 1996 LT4 Collectors Edition Coupe. I was thinking of replacing my stock sensor with a GMS brand. Its supposed to add 10 - 15 HP to your engine. Does anyone know anything about this product, is it worth the change, and does it do what the article says? Thanks for your help.

GMS MAF

Hey Hondo,
I think you should spend the money on other mods. These sensors can be a real pain in the A$$. A lot of people have reported knock retard, actually losing HP due to timing retard. In most cases it was caused by a lean conditon. I have also heard of surging problems at cruise speed. If you HAVE to have one, have them calibrate one that is 5% richer.I would take the screen out of your stock unit & invest in a cold air intake system like the vortex. You'll get Real HP increase, if you have not already done it. I would stay away from the GMS unless you have a MAF and can adjust rich/lean mixture. These OBD 2 systems are a little picky. Good luck- Scott
