If you spray in second gear you are missing on all the power in first gear. As mentioned above, if you want to make serious power you do not want a wastegate. Wastegates will just let boost out, boost is power. Speaking of power, how will you protect your drivetrain from all this power? Dont be a retard like all the others on this site. Everyone gets stage 4 clutches or twin discs...its all a waste of money, overpriced bullshit that just gives you no traction...You need a stock clutch, MAYBE a stage two..You dont wanna have too much grip, you want the clutch to gently engage throughout your powerband...thats the real way to make your setup last...you mix in a stock clutch with stock axles like Hedgehog mentioned, you will really get the good numbers at the track
