I would stick with what you have. 250 grand MPH means other issues, ball joints, U joints, Brakes, starter, alternator, and new tranny. Stick with what you have. You should have sucked it up form the start and did the studs while you did the other stuff. Are they pulling and milling the heads for that price?
im not sure im still saving $$ up right now, it will probably be another month or month and a half before it gets done. Im not sure if me heads are warped and need milling. im only puking a little coolant and thats when im running a canned tune on my sct x4 at about 2500 rpm so far i found a very well known diesel shop near my house and he quoted me 1500 labor to do studs. while hes in there should i go ahead and delete my egr? I already have a sinister upgraded egr cooler but if its going to fail in 100-200k id rather go ahead and delet it
