Review on 🔧 Enhance Engine Performance: Trans-Dapt 2566 Swirl Torq.Spacer Gm99-00 by Justin Spence

September 22, 2022

10/10 would buy again for another car

So I put this on my 03 8.1 Chevy and basically the throttle response is a bit better and I've noticed its performance. My shift points have changed and it's noticeably faster and has more torque. Also, my fuel economy increased by about 1mpg, but then again, I wore it everywhere.
