So I finally got my car back from the body shop (it was rear ended over a month ago), and got a chance to put on my exhaust and had it UpRev tuned by performance motorsport in smithtown NY.
Installed Mods: stillen gen3 intake, cnt test pipes, invidia gemini catback
1700 miles on the car, fresh oil change (ester), about 80deg out yesterday afternoon but not very humid, Mustang Dyno
Before tune: 321hp/246tq
After tune: 336hp/254tq
peak gains of 15hp/8tq
And as you can see from the dyno sheet it made up quite a lot of tq that was lost in the low end after the bolt ons. The car feels amazing and pulls really strong even in this heat, at night when it cools down it's even better
I don't have any dyno's before the intake, but most people saw about 20hp total from cat back/test pipes, so figure just under 300whp with just intake. This seems really high to me for a mustang dyno and I am sure a lot of you will agree, but
chuckd05 has similar results on this dyno and
backed it up with a completely different dyno (dyno dynamics).
I really don't know how much "adjustment" these shops can make to a dyno to have them read higher/lower, but mustang dynos are notorious for reading LOW, yet our cars are making great power.
A side note about the CNT test pipes: the brackets didn't meet up with the stock bracket on the transmission, there was a gap and the bolts ended up coming loose because of that, so it would rattle at 1800 RPM exactly (someone else complained about this recently), I just took off the transmission cat bracket instead of forcing the gap closed which would have caused a lot of stress. Hopefully no issues with cracking since the gemini has flex pipes. Not bad for $200 shipped!
