Electronic Fuel Injection

Carbureted & EFI For Increasing Performance

High-Performance EFI Auto Repair in Tucson

The expert mechanics at Trail Boss Off-Road know switching to fuel injection often improves the fuel efficiency and performance of older carbureted engines. In newer cars, replacing a single fuel injector with a multi-port fuel injector creates an intense, even flow of fuel on each cylinder when your engine needs it most. Feed your engine the fuel it needs with fuel pumps, fuel filters, superchargers, and turbochargers. Break out of gasoline only feed engines by adding a nitrous kit or cooling methanol injection kit.

To ensure the correct air to fuel ratio, Trail Boss Off-Road can add a new stock-height replacement intake manifold, cold air intake, and fuel rails. Never run rich or lean with a hood scoop, high-performance air filter, and new O2 sensor. Call Trail Boss Off-Road and talk to us about increasing your car's performance. When you want performance you need the auto repair experts at Trail Boss Off-Road located at 3631 W Ina Rd.

If you're ready to take your car or truck's fuel injection to the next level, Trail Boss Off-Road is ready with injectors, manifolds, fuel rails, sensors, and complete performance EFI conversion kits. From BMW to Audi to Corvette, Trail Boss Off-Road has you covered.

Tuning Old School Carburetors For True Muscle

Your muscle car may be starving for air! Bring it to Trail Boss Off-Road and find out. Because of operating losses in the intake runner and cylinder with newer unleaded fuels that do not fully vaporize in the combustion chamber, cars tuned to the manufacturer's specifications can run lean. Trail Boss Off-Road can diagnose if you are actually running leaner than the manufacturer suggested ratio of 14.7:1 air to fuel mixture. Bring your classic car to Trail Boss Off-Road at 3631 W Ina Rd to tune the perfect air to fuel mixture and correct ignition spark for maximum power.

    They were very courteous and knowledgeable. They even helped me out with a transfer case magnet that I had misplaced from my original housing. This was the only piece I was missing from putting my transfer case back together and Trail Boss was kind enough to provide one for me! Now I'm back on the road! Thanks guys!

    Installed a lift kit over the weened myself and had to get a 4x4 alignment. Not only were the guys at Trail Boss Off Road able to squeeze me in that Monday morning but got my Jeep done earlier than they said and was under the estimate quoted also. Great service and knowledge of all things off road. Thanks Jeremy, you have gained a customer for anything my Jeep needs.

    They did such an excellent job I couldn't have been more happier. I went back a second time to get more work done and not only did they again do a great job but fixed all the screw ups the place I had originally got work done did. If you want great, honest quality work done with great customer service this is the place for you. My hats off to you guys.

    They installed the rubicon express 3 1/2" lift on my 2015 Jeep JK. It looks awesome. I recommend them to do your lift thanks to Jeremy.

    Thank you for all your help with my diffs for the PTSD Jeep. These people went out of there way to help me. And they didn't know me. I have nothing but great things to say about Trail Boss.
