Wake up your Mustang with this PedalMAX throttle enhancement device from JMS. Designed to eliminate the lag between the pedal and the engine, you can expect a sportier feel and improved driving experience. This system does not interfere with your warranty and is CARB approved, making it the perfect upgrade for anyone looking to get more out of their Mustang.

Quick installation. Upgrading your Mustang has never been easier. This throttle enhancement device is plug and play and can be installed in your driveway in an afternoon. If you ever want to return your Mustang to the stock configuration, simply unplug the device. 

Easier than tuning. Remote tunes or custom tunes can be a hassle. Data logging, waiting on new files, and updating your device can make a tuning device frustrating. With the JMS performance booster, all of that is gone. Simply plug the system in and enjoy the improved response.

Ability to fine-tune performance. A control knob is included, allowing you to make adjustments whenever you want. This means that you can keep a stock feel during your daily commute and crank things up when you want improved throttle response and a sportier feel. 

Stackable. A great feature of the JMS systems is that they are stackable. This means that you can run both the PedalMAX and the BoostMAX at the same time for peak performance and incredible response. 

Meets CARB standards. The PedalMAX throttle enhancement device can be used on Mustangs in California or states adopting California emissions standards. The CARB EO number is D-816-6.

This product works great!!! I chose this as a first modification since it's covered under warranty, I'm sure glad I did. I have not dynoed my 2015 focus yet but my butt dunno tells me it's much peppier than before. The optional knob comes in handy too for adjusting on the fly but let's face it its best at full power!!

As an outside salesman I cover 2 states; driving up to 47K miles per year. As an enthusiast, I have enjoyed autocross for over 35 years. Getting a car that can be competent in both is a real joy. I bought my 2013 1.6 Fusion for a fun ride that would deliver good mileage. Autocross with a 1.6 turbo automatic was a bit frustrating due to slow downshift immediately after coming out of the hairpin turns. This PedalMAX module is like installing a new cam for us old school guys! It delivers higher RPM shift points, more run up so the turbo has an opportunity to participate. It is far more enjoyable to drive. The difference was felt within 100 yards after installation. It really wakes it up. I was concerned having more gusto would sacrifice the mileage. Keeping the cruise set at 65 mph on the highway resulted in 38.9 mpg with premium fuel. My advice to anyone wondering how to enjoy their Ecoboost even more; is to add the PedalMAX for more smiles per mile.
