I have a Texas Speed 570 horse LS3 with a provided Speartech DBW ECU-harness in my 69 Firebird. One thing that has always bothered me a little is the sluggish throttle response. I feel like more crisp throttle response would make driving the car even more fun. I've noticed there a couple of companies selling DBW add-on tuners. Anyone have any experience with these?
