Any 04 V owners that have the superchip programer with performance mode installed i have a question? do any of you guys have a problem with pinging above 4000 rpms because i do and i use 93 cheveron. now i sent it back to superchips to check the programer because with stock mode i get no pinging. they called me back and told me that there was notthing wrong with the programer and to take the car to the dealer with out the programer for the pinging issue so i did and like i thought nothing was found wrong so i called superchips again to inform them that the dealer did not find anything wrong with the car that it had to be there programer causing the pinging and they said no way and that no body else who has bought the same programer for the 04 V's have complained about pinging. please if you any info on this issue please let me know...thanks
