I've purchased a lot of diesel laptops before from other companies.

Heavydiagnostic.com was the BEST. I got my laptop in 2 days, fired it up and was ready to use straight out of the box, did some regenes, speed limiters and even increase the horsepower on my Cummins engines. Happy customer made my money back on the first scan!. 

Highly Recommended, Thank y'all .

Since I bought the diesel diagnostic toughbook from heavy diagnostics, a lot has happened. 

My business grew 35% in 1 year.

My mechanics are much happier and less stressed, which makes me more money :) . If my mechanic needs any assistance, he just texts or calls heavydiagnostic.com tech supports and with in minutes they assist him. 

My customers are now​ referring​ us to their friends and family . 

I feel blessed.

I already purchased a diesel diagnostic scanner from y'all and I appreciate all the tech support y'all provided me. So I am going to purchase another laptop. This is by far the BEST purchase I have ever made for my business. I work on a lot of on-highway and off-highway Cat's & John Deere. I love that none of the programs expire & that they're all full dealer level diagnostics. I was able to regen,dpf and flash my cat engines. I have no limits on what I can do.
