Cost will vary based on what is in the kit. Generally a basic progressive kit will be $600-$650 and can go up in price from there based on what may be added to the kit. Most cars are ok on the basic kit though.

and where does this kit get installed? i'm sorry for such a bland question. but i have a tune and could also make 250.

edit: just did research and i understand now.

With proper mods, fuel, and tuning, 250 whp is an easy feat. With your mods on 91+ octane fuel and stage 1 Qwik Tyme Performance tune the car should make 230's-240's whp with avg intake air, coolant, and exhaust gas temperatures. Better mods and/or fuel and/or colder air it will hit the 250+ whp mark. Right now on the oem tune the car will probably make 205-210 ish whp max in good air with good fuel then the limiters will kick in at higher rpm and pull 15-20+ whp out of it.

i can vouch my car does this

is it normal for my car to choke on boost, like full throttle it takes a little to hit boost and then the boost puts you in your seat?

yes, we need better air/fuel cooling and parts to limit the problems we have.
going full throttle, you either brake boost or let the boost build up while youre driving and switching gears, full throttle the car will choke and hates tons of boost especially at low rpm's or instantly..
