Local Porsche specialty shop in LA installed in 8 hrs. Avoided hassle and cost of $20-25k rebuild from dealer. My 997 S is now a "MONSTER"!!!!
im want to hear more - dyno yet?

I could not swing the X-51, so I'll be going that aftermarket route like RacerXTP. I'm and very interest in what your car dynos at and what ECU flash you went with? I'm worried like a lot others here that the wrong combo will cause a lost in power. I'm going to do the same with the PSE and aftermarket header and high-flow cats. From AWE site the cats make the biggest gain in power, assume that fabspeed would be the same..
