I plan on getting the stage 2 with toys upgrade. I'd like to get over 300hp to the wheels and wanted to know what AGP turbo upgrade would work with stage 2 with out alot of tuning. I have no shops around here that have the equipment to tune stuff like fuel/air ratio. I'd like something that I can put in and adjust the boost and not have too worry about fuel except for bolting on parts to make it work.
