1st gear is useless, and i get some chirping in 2nd, but after that its grip all the way. ive got the boost coming in progressivly so that it doesnt give you that harsh powercurve/torquesteer that you usually see with big turbos. it helps alot in keeping the wheelspinning down to a minimum. ive also got a quaife in the box, decent tyres, anti lift kit, etc every little helps.
