So, I replaced my boost solenoids. On map 5, it holds 17 psi. With new turbos and new solenoids, I dropped my 0-60 from 5.4 to 4.5. I still need tires. I think the car is fast enough for now. Now I can just focus on getting the rest of the car cleaned up. I have an M Sport rear bumper to replace my broken stock one, and I might eventually do M3 suspension arms and sway bars. I suppose I could also set aside some money to build that 408 stroker for my truck... I think I'm coming to terms with my HP addiction.
