That pretty damn amazing I would love to see a sheet.

In fact I have a problem believing that was on a Mustang Dyno.

Helix catted DP
Forge exhaust
Perrin pulley
GPmoto short ram

I am extremely happy with the numbers, especially considering I still have a cat and no stink, and am on California cheapy 91. Unfortunately my air-fuel ratio was at 11.8:1; I called Cobb and they suggested using the latest Stage 2 base maps, and ditching the short ram. Now I'm going to have to dyno this thing on 93 - because 2 points maked a huge difference in butt-power.
