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.

I purchased the 87PRX tune for my truck 5 months ago, and recently became curious about the 93PRX and purchased it now as well. For comparison, stock to 87PRX was a way bigger transformation than 87PRX to 93PRX. Both are really awesome tunes, but I would guess the 87PRX gave me about 75% over stock of what the 93PRX did. IMO the 87PRX is the way to go if you're conscious of fuel prices like I am. I'm curious to see how the mpg of the two tunes will compare. The transmission tuning itself is worth the money, let alone the power gains! Thanks MPT for your great work and customer service!!
Great Customer service they answered every question i had i actually live local to their shop and I placed my order and was able to pick it up within a couple hours and the tune for the 5.0 really brought it to life i did a 1,000 mile trip 2 days after Installing it and what a difference in fuel mileage it gave me that's definitely not the reason I bought it 😀 the tune also got the transmission shifting under control no more hunting for gears or skipping gears im happy i went with MPT!!!!
mpt is hands down the best company i know for tuning .. if its power you want its there/towing/fuel economy.. from first start to first drive you will understand why i would say that and you would agree. I have had several vehicles tuned by mpt and the drivability is so refined from shifting to acceleration and deceleration and a smooth idle is key and there tech support is aways on point if there any trouble shooting , from sales to tech to the calibration ther hands down a 5 star company .. first tune no revision yet 11.91 speaks for its self / tune only e50 Pr-x .. stock best 12.96 before tuning

By far the best tuning I’ve ever experienced. Truck absolutely came alive after MPT tuning and the transmission shifts so much smoother than stock.
