ive got a nistune board in my 32. the car was runny very rich, and sloppy before the nistune (fmic, full exhaust, splitfires, 14psi blah blah blah) cold starts were shit, and it idled like a dog until the engine was hot, now with the tune, installed and tuned by mercury motorsports in brizzy, power is more apparent thru the whole rev range, idle is very smooth, better fuel economy, gained about 10kw at the wheels, but its just a nicer car to drive. i would deffinately recommend this product, as it does such a great job, easy to tune, and very reasonably priced. adam
