I have a cts insight on my 04 (just installed), so far I like it. When I push the throttle, the gauges respond RIGHT NOW, their is NO lag with this unit. I installed a pyro, and am really happy with it. I like the fact that I can set parameters and it will warn me when things are getting to high or hot.
