can it be retuned and where can it be done. i have been hearing that with the cam im going to use i will need a custom tune to fix the idle.

 

No hypertec chips are not going to be compatable with the software used to program. Best idea is Ebay for that item...likely hurting performance more than helping. Bump your timing a tad and you will have performed exactly the same function as the hypertec chips for our cars. different story with the hand held program types, but they are not compatable with our vehicles either.
