Well I went out to the Dyno today. The first pull read 257 HP and 267 ft.-lb. or Torque, but they said the Torque seemed to spike so it was probably more around 250 if not a tiny bit more. The second pull read 257 HP and the torque spiked to 297 ft.-lb. of Torque. This was on a Dynojet. Has anyone else seen spike problems on the Dyno? Are my Dyno results comparable to any others? It was also pretty Humid. My only 3 mods are Injen CAI, Topspeed Pro1 Exhaust, and Non Resonated Test Pipes.

Any pics of the actual dyno? What gear did you make your run in?

Torque spikes are due to a poor RPM signal. I have seen people go to shops where they couldn't get a spark signal at all which means no torque readings.

From what i hear..... Dyno Jet is not the best and most honest dyno to test on because they are made for heigher HP cars and mainly measure acceloration. They do not have much if any resistance such as a Mustang Dyno, which sinulates actual road driving. This is all what a tech that has both dyno's told me. He said to measure best and most honest HP and Torque to not use the DynoJet but rather the "Mustang" dyno. And dont ask me cause I have no idea what the Mustang dyno is that is all a direct quote form him.....
