Proposition 65 (Safe Drinking Water and Toxic Enforcement Act of 1986) is a California law that applies to all companies selling products in California. Proposition 65 requires warnings if a product contains any listed chemical present above very low levels that are known to cause cancer, birth defects or other reproductive harm. Proposition 65’s warning standards are among the most stringent in the world. Proposition 65 is not a product safety law, but rather a “right-to-know” law. Businesses are required to provide warnings to comply with Proposition 65. These warnings are required to be in place for all products offered for sale in California.
There are over 800 chemicals on the Proposition 65 list, which is administered by California's Office of Environmental Health Hazard Assessment (OEHHA), a part of the California Environmental Protection Agency. The list includes naturally occurring and man-made chemicals. Proposition 65 warnings can be seen for a wide variety of everyday consumer products, including Automotive Performance products, and warnings can be seen posted throughout California in a variety of establishments such as hotels, restaurants, automobile dealerships/repair shops, and retail stores just to name a few.
To comply with the requirements of Proposition 65, this warning is present on all products sold by MPT.

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.
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.
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.
Great tune 93prx this has put my 2023 Raptor on another level thanks guys lokking foward for.the next update to.the truck
I was on the verge of pulling the teigger to do the whole Computer swap in my 2023 Powerboost, but glad I waited. As soon as I saw the new HP RT4 was available at MPT, I had to jump on it right away and glad I did. This is programmer along with the recommended PRX tunes really woke up my truck!!! I love it!!
