Looking for Power
 

I have 2000 Cummins that is stock with 170,000 miles. I have replaced the LP, IP, and tranny 10,000 miles ago. I also have 3 gauges (FP,EGT, & Boost). I'm getting a Pureflow Factory Replacement Raptor Pump (FRRP) 100 in September. I would like to get a chip or programmer. I was wondering what would be the best for me? Eventually I will get 50-100hp injectors but that is later on. My goal is 300 or so HP and a good all around truck.
