Ok so who should i buy from. Unorthodox or Fidanza. Fidanza is cheaper but is it better or just as good. also how good are the upgraded ECUs. not the ones by JWT but the one that are stock that are modded. Im lookin for a new ECU b/c i have an 85 and some of the guys said if u put a 87-89 model ECU in the car it helps and fixes the low idle at start up. I also need a new flywheel cause mine is wharped and its starting to shimmy in first and reverse. thanks. if those listed above arent that good then what are soome other ones.
