Well, she's back to carb again. I removed the Fitech unit, wiring, O2 sensor, etc. I installed a Summit 600cfm vacuum secondary unit because I have had great luck with them. A little float tweak, idle speed and a tiny bit leaner and she's purring. Easy starts, smooth acceleration and more power. I didn't realize what I was leaving on the table with this engine, this little truck really moves. For fuel I have the bottom feed from the factory tank to a filter, pre filter and E8012S low pressure pump, then -6AN up to the carb with a pressure gauge. My only issue at this point is dieseling on shut-off, not sure if there is a way to resolve that with my MSD unit/timing.
