the abs light will come on because the front tires are moving and the back ones are, that happened to me when i dyno'd my car too.

not uncommon to have those lights on.
you need to reset it by turning the wheel all the way to the right then all the way left. (or is it vise versa? :dunno: )

Thats because just pressing the button doesnt do anything. You have to hold it down for 7 seconds to completely turn dsc off

^^^ yup.
if you only press it, you don't disable the whole system.

No but he did hold it for 7 seconds or longer. just nothing changed... Right now im going to save up for the ignition upgrade.... and check my cat.,

If nothing changed you didn't hold it long enough. You need to push it in and hold it until both the DSC light and the slippery when wet light both come on and stay on steady. Then you are ready to roll. :)

LOL. New news, the guy at the garage can't send me the dyno sheets due to "technical difficulties". I'd have to go pick it up from him..
He's 20 minutes away though.
