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.

Shifting is so much smoother and truck gets off the line quicker. Highway cruising feels lighter, badass tune and great customer service, worth every penny. 5 stars.
I can always count on MPT for perfect fit parts. They are working great.
went with mpt based on their reputation, got 3 tunes, power gains are impressive with the prx tunes no more turbo lag, improved shifts and way more torque, also great customer service for information
First and foremost I am impressed and have been pleased with MPTs Customer Service. I’ve been wanting more kick in my pony but specifically a well known reputable team who specializes in the 3.7 engines. My pony has high mileage and pulling harder than ever quite literally with my MPT tunes. My car launches now and from a dig she not only breaks traction and pulls hard but she barks again around 40mph for a couple seconds! Absolute BLAST! If you’re debating on running this tune, you need to do it.
The SCT tuner in combination with MPT tunes and support is an absolute game changer. It facilitates an easy DIY way to install your tunes, datalog and select gauge layouts to monitor temps, boost, timing etc in real time. It’s a great little tuner.
