I just received my tune from mpt tunes and wow what a difference it makes. I have a 2020 and decided I wanted some more power and better shifting. So I decided to go for it. I went with the PR-X Tune - Available for 93. I ordered the tuner and 3 days after I received the unit they sent the tune. It took about 10 mins to upload the tune and I was off and running. In sport mode the truck is an absolute beast, literally will throw you back in your seat. I don't have any dyno runs or any info like that. The guys are great at mpt, very informative before you buy. I just wanted to give them a mention. If you're on the fence, don't be. You won't regret it.
