I think the dyno tuner is a GM parameter tuner that is afraid to go outside of the GM specs. Its odd, because they have a 800HP viper and a 1200 HP Vette that they have tuned from what they and others say. I need to find another dyno shop.

I don't recall if it got louder. I can't compare between the two N*'s either because I put a huge truck muffler on the auto swap in the 85GT. It is quiet until you hit WOT.

I haven't experimented with swapping around cams though that would be very interesting.

I wired my clutch switch to accommodate the LS1. The LS1 is wired backwards to the Fiero's.

It would be interesting to compare your tune with my Shelby tune. Somehow. Perhaps I should send Ryan another computer and then have the MAF dialed in here at another shop.

Shoot... you made me go look up how the Shelby is wired.

The Shelby needs a clutch switch that is normally closed, grounding the contact, and opens when the clutch pedal is pushed.
