Good to know, I'm sold on the oft again cause of the custom tune option.

Increased power from the OFT Stage 1 tune was inconsistent (some days it seemed like it had more pep than stock tune, other days it seemed to be the same or slightly worse). Running with the cat efficiency CEL might be ok, but I imagine it would affect performance (computer pulls timing?).
I went ahead and bought the custom E-Tune service Shiv offers through OFT and can say that it has made quite a bit of difference in the consistency of power and overall the car feel much peppier than it did with the stock tune or the Stage 1 tune (note that this is with this header and a few other bolt on type mods). Although I believe the E-Tune was ultimately worth it, it did take them more than 2 months to finish tuning and I had to constantly remind them that I was still waiting for an update (my typical turn around for datalogs was less than 48 hours).

Awesome! I'm sold on the oft now knowing I can do the custom tune which I will defiantly do. I will pick up the oft first then for stage 1 and then pick up the header and custom tune based on another thread that I made that suggested I do tune first and headers second.
