First of all, we are looking at two different graphs, one being 91oct and the other 100 oct.
The 91 oct made ~340whp @ ~21.5 psi
The 100 oct made 395whp @ ~28-30 psi
The hp taper occurs because the torque peak falls. This could very well be due to the limits of mechanical efficiency at those engine speeds, or, a decrease in turbo efficiency.
In any case, these numbers for 91 and 100 oct translate to ~398 and 462whp on a Dynojet respectively. Not too shabby!

Correct mine made 460ish and 400ish on a dynojet. I believe I made 391 and 335 on Shiv's rollers. Shiv can you please post up my weaker dynochart to show the consistency of the tunes.Originally Posted by Ted B

That turbo spools very nicely hitting 21.5psi at 4400rpms. What gear was the pull in?

how much is it to go to stage 3 if you are already 1+?
only thing extra is turbo and injectors, right? if not, what else is included?

321 stainless manifold, Lower IC pipe, Tial wastegate, New DP, MAF pipe, Turbo and injectors. Cost is in the 5K range depending on a few optionsOriginally Posted by gsujeff55
