Reprogramming A Superchips Flashpaq F5 Performance Tuner

Question:

I now have a service suspension code which governs my speed at 85 mph. I dont want to put the magnetic shocks back on because Im unhappy with their performance when off-road. Would any of the programmers you sell keep this from happening?

I believe this problem stems from you programming your Superchips Flashpaq F5 Performance Tuner - GM - Gas, part # SU2847, with the magnetic shocks on your vehicle. When you removed them your vehicle the tuner limits your speed because it believes that something is wrong with your suspension. You will have to contact Superchips with your Flashpaq model and serial number and they will take it from there. I believe they will have to reprogram it to stock and that should get rid of the speed governor. Then you will be able to reprogram it to your 2018 GMC Sierra 1500.
