I have a 2000 F250 7.3 pulling a 10K 5th wheel. It was a little weak and I called Mike who made recommendations for an upgrade. I had my own ideas but Mike had done hundreds of these upgrades and showed me my error in thinking. I am so happy with his expertise, his customer relation skills, his technician who did the work. I had the truck chipped, up pipes, turbo, and and oil link all done in one day. Truck performs beyond my expectations. Thanks Mike. - Bryon G. (5 star review on Yelp)

Ford 3.5L EcoBoost Turbo GDI engine from JASPER

At Monster Diesel Repair in Gilbert we provide only the best products to our customers and that’s why we are proud to partner with Jasper Engines and Transmissions. That’s why we are excited to announce the availability of the Ford 3.5L EcoBoost Turbo GDI engine from JASPER. This engine is available for the following applications: 2011 - 8/26/2015 F150, 2015 - 6/23/2016 Transit, and 2015 - 8/26/2015 Expedition and Navigator.

Mike at Monster Diesel was very helpful and did a great job finding the low power issue on my 6.4l Ford, complete vehicle inspection, and oil change. We were on vacation, from out of town, and took a chance by choosing his business, based on previous reviews of other customers. Simply stated, Monster Diesel knows what they are doing and how to treat customers professionally, efficiently, and with honesty. I would recommend you give them an opportunity to earn your business and respect too! Well done, Thanks. - Keith I. (5 star review on Google)
