The BTM is not really a good solution for timing either when you move away from a low boost setup. It just doesn't allow you much control and it will hurt you some places while helping you others.
You need a stand alone ECU or overclock to the stock one to raise the fuel cut. If you are still on stock rod bolts then I wouldn't go past the stock 6300rpms unless you are willing to chance the longevity of the motor. Anyway unless you have cams, even with a big turbo you won't be getting much power above 6500rpms.

I have the t3/t04 and ws thinking of doing 10psi on that, with bigger injectors because I know my 315's are not not going to hold. I see what you mean with the stand alone, but I don't think it's worth it with this motor. I might when I'm able to build the 5sgte. So when I go get it tune, I should leave the redline where it's at?
