is it me or does that seem low....

Seems a little low to me too. The car drives much better than before but I was hoping for some more on their dyno. The boost tapers to around 13lbs up top! I was told that's the worst he's seen...

Not sure what to say. I've got a little bit of an odd setup with headers/up and stock catback.

The first dyno was with Cobb 1.04 ots map. Just over 5,000 miles on the car.

Your setup pretty much explains the healthier torque figures vs hp. Tuned + TBE should net you towards the 300whp goal

The headers kept it happy through the middle and made great tq, but it had maxed the wastegate before 6k rpm and only made 12.7 psi at 6700 rpm... The stock airbox and catback may have been holding it back a bit, but these turbos vary wildly on what they'll hold to redline. If it had held 15 psi to redline it would have made 305+whp...

wow... I have stock header and up-pipe, with just a Titek Catless Bellmouth DP. to the Stock STI catback. running the Stage II OTS Cobb. I wonder what I can expect to put down on the Dyno. Anyone care to chime in with a guess.

That's weird how some ppl cant hold boost to redline. I have mine taper to 16 psi by redline and I think im close to 17 at 6k.

Maybe it's all that increased exhaust flow with the stock turbo making this one taper so bad.
