stock turbo need a boost controller?
im new to turbos sorry guys, got this car and already is stage 2 but has stock turbo. Do i need a boost controller or not for stock tubro? the guy has a greedy on there and took it off but left line in dash. He replaced it with a manual one from a evo... WTF! im a bit confused.... another guy tells me know and was driving it and that evo one was spiking to 20psi so he took it off. I adjusted the wastegate down some only boosting at 10psi now. But do i need to get a good controller ASAP or can i just adjust with the wastegate?
Help....
