Damn, boy, you get more **** done to your car in a few weeks than I do in 4 months! All of a sudden BOOM you have the Cobra MAF and JWT fuel rail (and 555cc injectors?). And again all of a sudden BOOM you have your turbo pipes and heat shields coated. Next week you're going to have a set of slicks and skinnies, an upgraded turbo, and H20 injection before I can even install my injectors and JWT ECU!

So if QuickSER can run 15psi on the DET ECU, DET MAF, and stock DET everything else, shouldn't you be able to now? You've got everything you need to turn up the boost. Do you have an A/F ratio and/or EGT gauge? Those will tell you basically how much boost you can safely run. Especially with 8.5:1 compression, you are set. Let's see that 15psi monster pull and 11.9!
