for 2300, buy yourself a turbo upgrade. Get either a 3147 (long backorder) or a 50 trim and run less boost. People will tell you this and that "buy an exhaust, or intake, or wastegate...blah blah." THe plain and simple point is that a turbo upgrade on a stock car will practically remove partial throtle boost, give you 300whp on a stock fuel system, and sound absolutely amazing.
Plus, when you add new mods, its SOO much better.
Freeing up some ponies by adding a 3" turbo back on a stock turbo feels good, adding one a 50 trim is unexplainable.
Oh, and 12.8 is easy on a good tire AND a GOOD driver
