Guessing HP

Completely stock 370s put down about 280 whp. Mine was 297 whp with a Stillen G3 intake, Berk HFC & Berk CBE on a Dynojet. After Uprev and custom tune I was 324 whp on the same Dynojet. My numbers are very typical with those mods and a tune. The tune made by far the biggest improvement in performance. The exhaust made the car sound great, but the tune improved drivability, throttle response, and performance.

Dynojet is too optimistic. I used Mustang Dyno and I got 261 whp for the stock Z.

Disagree. Mustangs are all controlled by the tuners settings. If the settings change so do the numbers greatly! A dynojet just spins a drum and you click STD, SAE or uncorrected. Nothing to mess with or manipulate! SAE is the entire worlds industry standard so make sure they click that and not the others. SAE are very accurate on a DJ if you take it to the track and get your trap speed and weigh your car before hand.
