True, but some idea is better than no idea. Also i have the newest strategy as the Ford dealer just updated it a couple weeks ago to go to the inductive update rather than the one i had which was buzzing the injectors for 30 seconds after shutdown.
My current mod plans for my 03 CC 2WD Dually are as follows:
fiberglass tonneau cover (done)
Turbo back 4" exhaust no muffler no cat
fuel pressure spring
gear vendors o/d (have from another application)
scanguageII (on order)
fuel pressure, EGT, Pyro guages
switch to synthetic fluids (which brand(s)?)
custom tunes (which ones?)
