No it will not require reprogramming, However there will be a huge change in performance obviously. We just had an 03 we put the 3" on, it produced 15 psi. Without the SCT chip it was good, but with the tune it was impressive.Supradude26 said:I just wanted to get some opinions on my next upgrade for my 03 Cobra. I want to put on a 3.1" pulley for the supercharger, however some people say the computer will need to be reprogrammed, other say it will not. Is it needed? The only other parts I have is a BBK intake and a catback system. Any advise would be great, thanks.
Yes listen to this guy! You don't need to dyno tune the car or check its A/F because he's guaranteeing that all '03 Cobra's are safe with a 3.1 and no tune, really!03Twinturbo said:No it will not require reprogramming, However there will be a huge change in performance obviously.
