OK. I've been considering doing away with the SCT chip and buying a tuner. The chip is fine but everytime I change something I have to have it reflashed. What are you running? How do you like it? What's the best part about it? Worst? My setup-331 stroker, 15# boost, 90mm mas, 60# injectors, 75mm TB. My issues-warm/hot start, factory rev limiter, WOT timing, WOT fuel, part throttle fuel. I have a wide band and data logger so capturing RT data is not that crucial. Mike
