My 4.10 gears threw off my speedometer by 10mph. I have a SCT Tuner from AM but haven't installed my tune bc when i bought the tune, i didn't have my exhaust set in the tune. I set it for Magnaflows with xpipe bc i planned on switching but decided to stick with Flowmasters. Anyway i can reset the speedometer without installing a tune?

Your cutback shouldn't matter in the tune. As long as you have your x pipe still in place and the tune is set to the x pipe it shouldn't be a problem. Unless your still running the stock chatted h and you didn't install the x then idk if it would work
