Upgraded turbos, fueling, injectors, tune, fuel pump, intercoolers, clutch, etc. Just to name a few.I wish E85 was available on the east coast in more areas. I would bump my compression to 12.5:1 and put down another 35-45 rwhp. It really is a wonderful thing for those of us that don't care about gas mileage.
So what exactly is done to get to a Stage 3?
My car pulls even harder up top. If we kept going, it would leave a larger gap. I'm pushing around 600 Chp.nice runs, m5s are pigs until 100 ish
