Just an update. I've been using the truck for a daily driver for a while now. Everything runs great. I'll be meeting a whole bunch of friends at the Pismo Dunes Friday for the afternoon so I need to check things over tomorrow and get ready. I have plans for more suspension upgrades and the new 9" rear end but that will be next spring sometime I hope. I'm just happy I can drive it around like normal and get decent fuel mileage. I don't have an odometer in the truck so I can't say what I'm getting for MPG exactly but it's not bad! With this standalone ECU you just have to make SURE that you go easy on the throttle when you are accelerating. If you give it more throttle then the truck can accelerate then you are just wasting fuel. It WILL pump more fuel into the engine when you press the throttle. With a factory engine and computer it won't put excess fuel into the engine, any more than it needs to pick up speed. So when you slam the throttle down in a stock truck the ECU won't flood the engine because it knows it can't possible accelerate more. But with an aftermarket it will. I know this because when I fill up I can tell if I'm using a ton of fuel or not by how much I am putting in the tank. When I baby the throttle (still accelerating normally though - just not really fast and irresponsibly) for a few days and go get fuel it takes a lot less.
