I got a,, well,, it's in the title, I brought it stock two years ago and so far I've installed a HDI 3 port ebc connected, blocked hoses 10 + 23 and 23 on inlet side. Removed all the bulls... Out of the driver's side front guard for the stock air intake and left in take open from the guard itself, cold air. Removed the stock muffler at the rear diff and have left it open from there ( sounds like a beast). Car absolutely screams, having boost adjustable and am running the car at around 16.psi, no other work done rest is stock. Does anyone know if I should do re tune or is it fine as is, it is running immaculate and doesn't miss a beat, or will the factory computer relearn and self adjust.
