Thread: Car was way faster before the gears were programed

No that is incorrect. The differential final drive ratio is always 3.29. It's the sprocket size that causes it to be 2.93, 3.29, or 3.69. Go back in, put in 3.29 back in that field in hptuners and on that same page there should be Sprocket Ratio that will be at something like 1.12xxx. You need to change that to 1 and then program for your correct shift points if you haven't already done so.
