I don't think anyone is questioning your integrity. IA is a top shop and I have bought stuff from you guys and shop talked with Stephen about the 997TT. At what rpm did you start the pull - floor the gas? It could explain why the tq peak looks so different.

I think we figured it out. WG problem. The boost was down to 10psi at redline, so that would be an issue. My original question was leading to where that was due to the turbo running out of steam (which has to be close for the K26/6), or the wastegate leaking, and everyone agreed it was the wastegate.

2000rpm, then floored till redline. I have hundreds upon hundreds of dyno runs under my belt.

Yes Tony Garcia. He is one of the guys who has probably done and tried everything imaginable to a 951. 450rwhp on a sub 2800lbs car like that would be just incredible. Good luck!

So just get that Tial hooked up Doc and run her again. Should make a big difference. Regardless of chip tuning hurting the spool up, that Tial will be locked shut during spool up and will make a big difference as well.

So the low end and top end can both be greatly improved once you get the Tial on there. I know in my beginning days on here many would say a new wg was one of the best modifications.

What are those custom chips?

Doesn't that dyno read low though? I have some buddys who have ran stock evos there and only ran 220whp. They should be at 230-240whp and have done that on other dynos.

Not anything relevant to why your car is acting like it is, but your car could be putting down more then 270/260. Just food for thought.
