Does it matter what headers I use with OFT?
 

Right now I have stock headers and was looking to get Gruppe or Tomei headers. I've heard OFT will not give you the best performance with other headers other than their own. Is this true?

Also does the tablet come with the latest tune or does it need to be updated?

other headers will be fine especially other uel like tomei or grupe s, for the money probably go the gruppe s.
The main thing you need will be good quality fuel especially to run the ofh specific tunes that are quite agressive, but the standard ots tunes will wok fine on most uel.

id probably avoid the el cheapo headers like 1320 or cnt their likely to give you fitment issues , the gruppe s is a great header for the money

other uel ok as well

just avoid the ace or the nameless if you want to use standard oft el header tunes, your not going to get max benifit out of long tube el headers with ots oft tunes

OK I understand a bit of that haha as long as I can get the Gruppe S headers and flash a Stage 2 tune and be fine, I'm OK with that.
