River City Diesel LLC at 1360 Spring Bay Road Ste A, East Peoria, Illinois.

I've done business with Josh Davis and River City Diesel since it's inception. Starting with some mild Stage 1 injectors in a 6.0 Excursion the products & service have been top notch. Over the yrs and many steps up from Stage 1 nothing has changed. For high quality products and service at a fair price look no further. Amp

Diagnostics and repair on a rough starting 7.3L that I had taken to the Ford dealer and after 3 days they had no idea what was wrong. Within an hour of having it on the lift River City diagnosed it accurately. They then replaced 8 injectors, repaired some small other items, and had it purring like a kitten. I agree with another reviewer that it can feel like they are hard to get ahold of at times but for the right work done right the first time ? I can deal with that.

If I had a 6.0 I'd let them tune it any day. 5 times if they wanted to.
