Wow!!!

This is my second purchase through MPT. My first was for my 2017 Raptor a couple of years ago. I sold that and bought me a 2023 Raptor and had to get another tune as I was already pleased with the first one. I went with the 87 and 93 tune but have only used the 93 and damn this thing pulls!! Even in normal mode it’s good but in sport mode it’s a whole different animal. If you are hesitant, just pull the trigger. You will be very happy with the results. Oh and their customer support is always fast to assist and have been awesome. Great job Jose and the rest of the crew.

Great Increase in Power

this is my second time purchasing a tune from MPT, and it's just as awesome as the first one purchased! The tune really woke up my gen 3 and it doesn't feel as sluggish like it was in stock form. Customer service is always top notch, and i always have confidence in their knowledge and execution.

Top notch

I have used a cobb accessport, 2 sct x4's (2 different trucks), and now this hptuners rtd. I'm not one to be content and stay with something. So when hptuners and mpt said no more tuning under the hood I had to jump and order a rtd. No regrets. Love being able to do everything I need to do for tuning from the convenience of sitting in my truck. No pcm unlocks, no swapping pcms, and no under hood tuning. What more can you ask for? And as always you can't complain about the customer service, fast shipping, and awesome tuning from Mike and the boys. They dont skip a beat. Josh at mpt was on the ball when I told him I needed to upgrade my device. Signed,sealed and delivered in a couple days. Dont second guess yourself on talking to Mpt and putting a order in. Definitely well worth it.
