I'll be honest, it's hard to beat the OEM turbo for that goal.
If you want something better, I personally think the Duramax Tuner/Calibrated Power Stealth Mach 1 (64mm) or Fleece Cheetah's are the best you'll find. The single plane wheel on the Stealth does give up a touch of power up top compared to say a Dan's, Stainless, RDS etc but they more than make up for it by their response time and drivability.
I am the type of person who would rather give up 10-20hp at peak for more average power and better street manners.
