I have an 04 Roadster to which I've added Borla headers & exhaust, Invidia test pipes, K&N intake, and Kinetix SSV. I assume a reprogram is in order but from whom...Jet Performance, Technosquare, or an AccessPORT? I'd like to hear from N/A Z owners with similar mods who have reporgramed.

Also... anyone notice the test pipes or cat deletes sounding raspy between 3K & 4K? Maybe I need a different type or brand?....WDYT?

 

try UNICHIP I heard its pretty good with any mods!

 

i believe this is in the wrong forum
i'd recommend you look into uprev osiris
