New and need some serious help

[twack]

Again brookdale is not the place you want to take it, they know nothing about cars with aftermarket tunning and turbo kits. You need to take it to MAP or DB. besides if you take it to a dealership it will be the most expensive place on earth to be, and they wont even know what they are doing

edit: if your running 10 psi on a 420a you might want to try and get that down to 7 or 8 until you know whats going on so you dont blow shit up, and make yourself mad
