I have a appointment tomorrow at a local shop to get dynoed. Im completely stock. Does elevation have to do with anything on horsepower or torque because i know it does on the track? The only reason im doing it is because I just ordered an intake and tune so I want to see how much of a difference it really makes. What should I be putting down stock?

yes elevation does matter. The SS/TC that were dynoed where i use to live "Nova Scotia, Canada" were hitting around 235whp on the dyno. We have higher elevation then most dyno's in the U.S. so we get alot lower readings.

Yeah because the elevation here is about 3800ft above sea level.

Well i just got back from the dyno. It was a mustang dyno and the best I put down was 250 hp and 277 tq. I think thats pretty good for being completely stock.
