Tunes Starting At


For years we have had customers not financially ready to commit to a diesel conversion project, but still wanted quality, professional tuning done on their vehicles. Diesel Toys teamed up with the best-of-the-best in gas/petrol tuning business and are pleased to be part of the KDMAX PRO ® Tuning Group. The KDMAX Pro ® tunes are simply the best tunes you can get for your Tacoma/FJ Cruiser, 4runner, and Landcruiser. Based on years of research and development, these tunes will completely transform your vehicle. If you're wanting better mid-range torque, increased throttle response, more power to pass on the highway, and better fuel economy, this is the answer.



Professional Tuning Done Right

Not all tunes are created equal. At Diesel Toys, we have been professionally tuning vehicles since 2004 and have a massive amount of experience with tuning vehicles.  A professional tuner ALWAYS retains your stock files in case for any reason you need to return your vehicle to its stock configuration. This is good practice and provides an extra level of insurance to the vehicle owner. 

No More Hunting for Gears

Anyone who has spent some time behind the wheel of a stock 2016+ Tacoma knows the frustrations of stepping on the accelerator only to experience tepid throttle response, terrible mid-range torque, and constant up/down shifting of the transmission. The KDMAX PRO tunes completely transform your Tacoma with results you have to see to believe.

I was blown away at what the guys at Diesel Toys did to my stock Tacoma with the gutless 3.5 v6. If you're on the fence about getting a tune, dont be. Completely transformed my ride for the better. This is how it should come from Toyota! 


Sean P. San Antonio, TX

We tuned our (new to us) 5th gen 4runner using Diesel Toys and could not be more pleased. The price, professionalism(wife was there maybe 20 minutes total), and excellent finished product is just astonishing. Do yourself a favor and tune your truck with Diesel Toys. You will not be disappointed.

For the past several years, we have sent all of our post-sales customers who ask for performance tuning to Diesel Toys. They are the only company with the knowledge and skillset at this level that we trust sending customers to.
