For those who have acheived (i assume its possible since I've heard of it happening) 400+whp on the stock turbo I assume you've done fuel upgrades. What type of IDCs are you guys seeing on your injectors if not upgraded when you start closing in around 350whp. Ive heard of some guys managing 350+whp on stock injectors and was just wanting to know at what point on the stock turbo power levels you guys are upgrading your total fuel system. Thanks!
