Yes it does! Yeah it's a little disappointing that Cobb's OTS Stage2 produced basically the same thing as the Stage1 protune I got from Cobb back in April, but I expected it. However, comparing Stage1 vs Stage2 (only real difference between them being stage1=cat, stage2=HFC/test pipe), they seem to line up pretty well. I think if I had gone with the Non Lowered Waste Gate map, I probably would have been closer to 320whp. Then the difference between Stage1 and Stage2 would have been more apparent.
Stage1: 305whp
Stage2 LWG: 315whp
Stage2 (estimated): 320whp
Assuming I would have gotten to 320whp with 3 more PSI of boost, then the "test pipe adds between 10-15hp" statement would hold true. Either way, once I go get retuned, I'll hopefully be at 330whp since I'll be running 26-27psi and Calvin (Cobb Plano's tuner) will be working with a 3port. Hopefully that will give him enough control over the boost that I'll break 330whp, which was my goal from Day 1.
It's been exciting every step of the way and I can't wait to see how it all ends up! Then maybe after it's all done, I can go about life again trying to find a girlfriend and writing code in my spare time, lol!
