what year is your ride??? steve_hellums posted a thread about putting his traction control fully on and off by seperate switch but it only works on mid year 04s and up. i to have thought about the rpm window switch contoller but..... what hellums has done cost him 40bucks where as the controller costs 100+ and you still never no if your going to break them loose even with the rpm controller. although it would still be nice to have the switch because its not good to run the nitrous to soon and its definately not good to have it running past redline. Psuperti has a 75 shot on his car and has had no problems!
I guess i didnt really answer your question haha!!
