I recently installed a TCI 350 turbo transmission and my speedo is way off. I used the stock speedo gear and im sure i need a different one. Is there a way to calculate which one i need due to my different transmission,wheel size, and rear end ratio?
Also does the grand nationals have a governor or speed limiter? when im doing 75 mph the speed is showing 110 and if i gas it and it goes up to 125 on the scanmaster and it shuts down then picks up and back and forth. Is it determined by the chip im running?
