1.8t Challenge Dyno plot
Just got this from Jay at primedia... go stock k03!
Dyno runs were done at GIAC's facilities here in socal in August.

doesn't look anything like AMS's Maha Dyno... big difference in drag/braking by the dyno. Huge difference when torque comes into play, so not sure what's causing that.

Dyno readings will always be different
since every dyno setup will have a different load ramping setup. I noticed this since I have put my car on 2 dynojets, 1 dynopak and on the GIAC dyno plenty of times. I ended up getting the same hp readings on the giac mustang and the Harman Motive dynojet but the tq readings were much different.

Well lets see
GIAC dyno tuned my car at 385 whp @ 22 psi with the Innovative turbo(60-1), then I dyno'd for the 1.8t challenge with the GT35R at 378 whp at 20psi on a hot run and then dyno tested at harmon motive at 385 whp at 20psi on a cold run. Only difference I saw between the 2 shops with the GT35r turbo was the jump in tq which was 278 on the mustang and 328 on the dyno jet.

until then i won't believe the claims lol. and i want the same car to run the non-injector tuning too, street program pump gas, nothing above 93.

oh i knew the load was way different but i never figured that it would account for that much
difference in when the torque band came in. It's why i wanted to see what GIAC's dyno measured vs AMS. Gives me an idea of the different dyno setups.
