There is nothing wrong with wanting a smidge more power without breaking the bank or additional parts on your truck. Step just beyond the factory power rating of your 2003-2007 Powerstroke with this Stage 1 61MM Turbo Time USA GXR turbo. The slightly spicy snail promotes horsepower ratings between 400-500 when used with recommended 175CC injectors, in addition to reduced spool time and power efficiency. Featuring a billet 61MM compressor wheel, and AVNT (Advanced Variable Nozzle Turbine) you can personalize your power band to work either for towing, or just a bit more grunt for your daily drive. Available powder coating options in 8 different colors, your turbo can be a unique or middle road as you want.
