Procharger Tuner Kit
d-1 has a better design and will put out much more power....even if you are not wanting to put out max. the d1 is still more efficient...the tuner kit, i belive, doesn't come with fuel stuff, so you can buy your own, hince "tuner"...i'm not 100% positive but am pretty sure...i thought it was on their website
If you are a street car the P1 is better because it will spool up sooner and provide low end sooner and be more fun on the street. If your looking for all-out best times at the track above all else then get the D1. The tuner kit is for "tuners" who do their own fuel system upgrades and is what everyone I know runs.
So, if I was to get my own pump, injectors, and custom dyno tune, then I should go with the tuner kit? And if I want more top end, the D-1 is the way to go?
