Tune after bolt ons?!? & DFW Uprev??
Hey guys, so far, I have a pair of K&N cold air intakes on my Z, and I have LT headers & a TDX Catback coming from FI. I was wondering if it was necessary to get a tune after these bolt ons? & what are the dangers of not getting a tune? (going to get a tune anyway, just want to know the pros & cons) and does anyone know of any places in the DFW area that offers UpRev?
