Here's my dyno chart. I really can't seem to get it to scan better, so I'll interpret.
310 wtq @ 4440rpm, 280whp @ 5250 rpm
The lines are pretty wavy beyond 5200 rpm because the car was so hot on the dyno. The high-flow cat in the downpipe choked the car up top, and now that's gone but I'm not putting it back on the dyno just yet. We did a road tune today, and the car is running so smooth, and still pulls like a bandit. I would guess I gained ~10hp by ditching the cat.
