i think me and kas have alot in common except ive mannaged to kill mine. i would say that everytime ive drove my car and its warm ive redlined it ill keep it nailed in 4th and 5th even from as low as 3000rpm to the limmiter, overboosts loads to about 21psi. funny thing is that my engine seems fine, no smoke or horrid noises yet the box couldnt handle my mega quick changes 8)
