I decided to remove the tune before taking it into the dealer. It only takes about 5-6 minutes, so I did it in my garage just before I drove to the dealership. The trip to the dealer was short and mostly on two-lane roads, so I did not have any reason to try to open it up.
After picking it up from the dealer, I had to run a couple of errands. (Big mistake!) Let me say it was TOUGH to DRIVE! This was the first time I drove it any real distance after the 37s and WITHOUT a TUNE! It felt slow and sluggish. It was not enjoyable at all and I can really relate to the other guy complaining about the lack of power on his brand new 2019. With all of the other "performance" mods I have, I still felt like I could not get out of my own way . Even the exhaust sounded tame!
Needless to say, I immediately put the tune back on when I got home and took it for a quick drive to make sure it was back to normal. Whew!, was all I could say after I got back!
For those who have not experienced an MPT 93 PRX tune for themselves, it is the best $695 performance dollars you will ever spend on your truck!!
