Ok, I have an AP2 with 70,000 miles, I have Greddy Racing ISO 8 pre-gapped Spark Plugs, 70mm Invidia V3 Dual Exhaust, 70mm Test Pipe, Greddy Type R-S BOV, and a TuboXS manual Boost controller. I am thinking I will see if I can safely squeak out 9-10psi on my stock motor/HG. Going to get it tuned to by P-Tuning, hoping nothing abnormal happens (over boosting etc......), I hope to be between 300-315WHP, what are your predictions?

I'll be posting my Dyno numbers on the 4th

 

I think you will be a bit over 300-305 at closer to 10 psi, and 290 at 9psi. I really hope you don't run into the overboost problem. I truly have not figured out how and why that works. I am going to run this set up but I got an AP1 and using a high flow cat. Why did you chose the 1so 8 over the 7's.

 

Well, you have an AP2, a larger exhaust and a test pipe. I have an AP1 with 2.5" dual and a cat and I got 276.2 at 8.5 psi on the same dyno you are going to be on. That's almost 100whp more than what my car would do NA. If you don't overboost you should easily beat my numbers. I'm gonna go with 295 whp on one of the lowest reading dynos on the east coast, but I'm gonna be pulling for you to break the 300 whp mark.

 

You should be right around 300 I think. Keep us posted

 

I went with the Greddy ISO 8 plugs, becuase I believe they were recommended in the Kit instructions

 

Use that TP that you got. Read my latest post. Its not what's causing my boost creep.

 

Sweet, I will def install it then, let me find your lats post
