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.

Made my truck a whole new animal. Thank you
Decals are great quality, easy to peal, easy to apply, and looks awesome.
I was running a another company's tune for 3+years. I decided to buy an mpt tune. Wow, what a difference, night and day. I can be going 35 and floor it and it smokes the tires, it's Never don't that before. The competitor's tunes are basically canned (generic). I'm impressed.
Couldn’t be happier with my MPT tunes! I’m running the 93 Tow, 93 PRX, and E30 tunes, and each tune has its own noticeable power increase. The truck feels stronger every step up, and MPT’s customer service was outstanding, answering every question I had. Highly recommend them!
I was expecting MPT to be great and they are phenomenal. Fast tune delivery and great communication. My 16 f150 2.7 with the 93 PRX tune feels faster than my brother’s 16 f150 5.0 tuned by Lund on 93. Smooth and aggressive power delivery, and the transmission tuning was more than I thought it would be. Shift points, pressures, and torque converter adjustments were perfect. Highly recommend MPT for the 2.7 ecoboost!
