i have a 05 roadster, i have 20's on back by ten inch rim with 275's on the back i think if i spray form the second i hit second gear on i will have no problem with traction, i just don't know if its a good idea to hit trac. control while spraying because of timing and all that so i would like a way to just spray second on when armed isn't that what a controller would do. and yes not a good idea to run nitrous all the way to redline. and yeah i will not go past 75 shot
