Ram 5500

**Damion143** · 06-19-2018

Hello, I have a 2016 ram 5500 with 235000 miles on it. I recently had the truck deleted and put the RaceME Ultra Tuner in the truck only about 4,000 miles ago. Last week it developed a miss and had a little smoke from the exhaust.

After some research, I determined I had a bad injector. i went ahead and replaced all 6 due to the milage on the truck. After replacing and setting valve lash truck ran ok on the test drive it started acting up again. took it to the diesel shop and they did a cutout test and found that two of the injectors weren't working #2 was dumping fuel and #4 was not even working at all no response.

They are possibly thinking that when they wrote the tune they wrote it for a pickup and not a cab and chassis truck that I have.

Any thoughts on any possible directions to go would be great thanks.

The box tuning on a Cab & Chassis makes them go crazy. You need to just run a delete tune as the Cab & Chassis is not like the consumer 6.7L Cummins.
