Just wondering if anyone has the SCT custom tune thru modular depot. If so how do u like the result, and how much is the charge if you add on mod's later and need the chip to be re-tuned. What I have now is shown below but in the near future I am going to pick-up a set of head possible cams plus drag radials. Once peice at a time is all I can afford, I might possibly s/c instead of cams. Either way I am going to need a re-tune if I choose the chip. Any advice would be great.
