OK here's tonight's results with last year's added in. All numbers are at the engine and assuming 17% transmission loss.
The short of it: 127 HP and 258 ft-lbs torque!!! That's 37 hp and 109 ft-lbs torque higher than stock.
The long of it: Last year's were done with the Wett chip alone. This year I have a TT cat-back and a bleed to 19 psi sustained. There is a constant 10-12 HP gain across the entire rpm range. What's more the useful HP is extended out to 4500 rpm.
I kind of blew it, though. I adjusted the bleed between runs so I could compare 19 with 24 psi. I didn't have the guy check it before the run and I didn't bleed enough. Run 2 is at 20 psi, which is not enough to even compensate for the "hot engine" fall off.
Overall, I'm pretty pleased with the A3. My need-for-speed addiction is still pretty strong. I think there's a 2.5" downpipe in my future
