Sharif assures me it will be better, its going to be stiffer, but is designed to hold alot more power than the JWT.  I have friends with different cars running the RPS 6 Puck and they really rate them, very firm pedal feel, but good performance. 
  
Huge dip in the power band was a problem created by another installer, im afraid.  A busted vac hose to the boost control solenoid.  But thats another story entirely.
