Then, we just took off the test pipe
I repeated this test at the track, and saw a 2.4 mph gain in trap speed (for equal 60' times). But on the track, I was running race gas with 25psi boost. On the dyno, I was using pump gas and 21-22 psi.

thanks everyone, I tested taking the cat back off as well. At the track I gained 2 mph on average, on the mustang dyno only picked up another 7whp accross the board. So best with the cat back on was 11.5 at 117 and with it off 11.4 at 119

this a long shot question, i'm really looking forward to taking your path on my evo IX. im sure you went through a lot of tuning to get to where your at. would it be possible that i could contact ams and they would have it flashed for the way you have it set up at 100 octane?
Dan from what i can see, looks like your having lots of fun with this daily driver!! I like to say that your drviving abilities are extremely impressive
Im sure that when your driving the Evo IX is alot more fun to enjoy the ride rather than the lighting fast VIII
I wouldnt be surprised to see you run 10s with the stock turbo..OH oh, be careful Curt Brown

Anyhow, did you (Mr. Dan) remove the internal backpressure muffler valve, or does the IX even have them?
