This is an excellent point. The stock turbo once you open up the intake and exhaust and bump the spike to 28psi, it is a finicky chore to tune such a fast spooling turbo. I prefer the slower spooling units for that exact reason. They are easier to tune for spoolup, peak boost etc. IMO the stocker even in the 10.5cm2 form spools to fast once these mods are done, you want something bigger at that point.

Definitely what I am interested in seeing is this turbo on a much less modified car. Your results are great, and at 22 psi thats really impressive. But I wanna see what kind of 1/4 mile times you'll be able to throw down with BPU's and some other light supporing mods.
