Just picked up a 2020 Raptor. Only had gm diesels for the last ten years and all my tuning experience is with that platform. That being said, I raced the wife last night in my 16 gmc duramax and she beat me pretty bad. We switched vehicles to eliminate the driver variable and came out with the same result each time with the Dmax winning easily.. So on to the next question. Now I want to tune the raptor to keep up. My dealer is offering SCT Livewire dealer installed with warranty. Unfortunately I was leaning more towards the MPT, gearhead route. Absolutely need trans tuning which I'm not sure if the live wire tune offers? If I let the dealer install the tune can I then write over it and return to the livewire tune if I needed warranty work? Any advice would be great. I have searched extensively and I cant even tell for certain what tune is avaliable for the 2020 with trans tune. Thanks in advance for the help..
