My FRPP 3.73 gears are going in next week. I plan on installing my BBK L/T's, BBK X pipe, and magnapacks around the middle of March. Do i need a dyno tune after installing the exhaust? I plan on putting a procharger on in May or June and was wondering if the tune can wait till the procharger.
the better flowing exhaust will lean you out quite a bit. I would get her tuned. I know it gets pricey, but thats the name of the game brother! Better safe then sorry!
