Tuner To Bypass Fuel Management System In 2018 GMC Sierra 6.2L

Question:

You guys are recommending edge gas evolution CS2 for my 2018 GMC Sierra Denali with the 6.2l Was wondering if it will eliminate my speed limiter and my FMS.

I do have an option for you but the The Edge Gas Evolution CS2 Performance Tuner- Color Screen part # EP85350 is not going to bypass the active fuel management system.

I recommend Edge EvoHT2 Hand-Held Performance Tuner - GM part # EP26041 for the 2018 GMC Sierra 6.2L that will allow you to stay in v8 mode and also adjust the speed limit up to around 200 MPH. If you do adjust the speed limiter you will lose all cruise control functions.
