I have the single Needswings and I feel the same as you do. Then I got a Code3 pulley. Now I have a serious problem. No traction! You'll reach the same point soon. So, what to do next? Wanting even more power but not having traction with the power you already have. So I bought Michelin Pilot Sport Cups ($$$$$) and you know what? Still lacking traction. Just letting you know. So who has the faster car, the one with more power and less traction or the car with less power and more traction? I don't know about you but this is the type of problem I like having. What a fast, fun little car.
