I have a 63k mile 426 Stroker with a Stage 6 85mm turbo kit. Trans is a Paramount Super Pro. Jerseyboy is tuning it but I’m having idle issues. We’ve gotten some logs but can’t seem to find what is causing the irregular idle. Boost gauge shows it loses vacuum but I’ve hooked a smoke machine to everything and their are no leaks. The tuner is a Trinity T2 and it has a Fore Tripe Pump with FC3. I ran the vacuum block between the brake booster and intake manifold. It will idle fine for over a minute then start cycling the idle. Any ideas would be awesome.
