Yes I still have A/C and P/S. The plate system is a wet system which is safer. Like I said, I do keep an eye on my plugs looking for a lean condition or detonation. I also use a scan tool with data stream to monitor O2 sensor voltage while spraying. Like the other responses, I do plan on upgrading fuel (pump regulator and rail) at some point. I want to go higher (the thrill of 75 shot is gone), but not until I can upgrade fuel pump, rail and regulator and some dyno time. I was hoping for low 14's but my clutch wouldn't hook up for a good launch. The 95mph trap speed is good for a low 14. Right now I don't have the bottle heater or guage. I could be below optimum bottle pressure. So I leave it at 75 shot until I can upgrade to be safe.
