I have a new Burb (Well I am picking it up next week) it has a rebuilt 6.2 and is mostly stock except a K&N filter. I would like a few more HP and was thinking exhaust and pyrometer (I know this won't add power, for injection monitoring). I am assuming that a turbo kit is more than I want to spent. Next is the lift, If I went with 35s wouldn't I need driveshafts? How much can I expect to spend?
