190 to the wheels or on the engine??? what other mod is been done to your ride???what kinda gas U are using??
do some dyno runs get the base number see what U're running now and how much whp U want and how much U can affort...
like what ikkuy suggested they are all gd
if U want a better respond lightweight pullies, flywheel, and a smaller pully for your charger, suspension setup. the lists can go on and on.ask if u have ne questions

one word of advice
always back to basic
U can throw tons of money into your ride and is still slow
its only as gd as the one whos behind the wheel
