Jesse and his crew has gone above and beyond for me and both of my trucks. have ran 5 differnt sets of WDI injectors and never had an issue. Their tuning is absolutely incredible and it’s all both my trucks run. Everything has always arrived in a timely manner. Most importantly, their knowledge on the 6liter platform and injection system far surpasses other company’s. Thank you guys for everything. Keep doing you

I want to give a huge shout out to the crew at Warren. From the moment I walked in the door I was welcomed with a hello and how may we help you. Special thank to Mike their Machanic . This guy took me on a full walk through from start to finish on how my injector work and how they build them. If your looking for a place to have your truck worked on, I highly recommend Warren diesel to do any of your upgrades, from mild to wild. Thank you all at Warren for the great service you provide.

Nothing short of a spectacular experience with Jesse and his crew. I was having issues with injectors I installed awhile back and happened to be traveling close enough to his shop so I stopped in to vet some live tuning. He did a bang up job and I can not thank him enough for what he did for me. No just tunes but advice, knowledge, and hope for humanity that there are still good people in the world. The type of guy that a hand shake over a cold beer is a done deal no questions asked. If you have read bad reviews and are having trouble with his product I highly suggest to call or even better get to his shop. Thank you Jesse you've earned my trust for life.
