Throttle response?
 

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?

I had a tuner like that on my Ram daily driver. It rescaled the TPS so it ramped up faster. Made the throttle response quicker. It also put me in limp mode a couple times so I took it off.

You can get a tuner (person) to do the same thing, or get your own software to tune the ECU yourself.

I have no experience with it and there are probably others on the market, but I want to try it and my car is still in production
