I'll run whatever Larry Macedo uses to make my car run right. I don't care what he uses as long as it runs right. It looks like he suspects the 1996 PCM he sold me of causing electrical problems and with the VEC2 he would have to have the PCM flashed to give my car the 1,000 RPM idle the special Lary Macedo designed cam needs. My car died before and almost died a lot with the 700 RPM idle of the 1996 PCM this past summer. The AEM does provide an easy way to get the idle adjusted. Whatever Larry uses to make my car run right - really right - with no surging and bucking, no high idle hang up, no codes being thrown, and correct idle for his cam - will make me happy. Since I'm not going to get the "at least high 700's in power" as originally promised, I expect more from the rest of his promises and it's up to Larry to decide how he wants to make my Viper really right since I paid him a total of almost $28,000 back in June of this year for a completed job I thought.
