Rob has UPREV tuned many cars and it’s no secret that with proper tuning, simple bolt-ons can yield significant power gains. David T. came to ZCG for a Bassani exhaust and tuning for his Z33 and left with some impressive results. The dyno chart shows a large improvement in peak hp and tq(+14hp/+20tq) at the wheels. Look closer however and you can see even more gains throughout the entire rev range. At 3700rpm David’s Z makes 21hp more and enjoys a HUGE jump in torque from 215 to 245!
