Ignore the monsoon, we have gotten an absurd amount of rain over the past few days.

21 ram getting some maintenance done this evening! Really looked forward to installing the new Fleece Performance Engineering grid heater kit! One of the most thought out put together kits on the market, everything was labeled and organized!

Took the shop truck out to do some dirt racing this past weekend and squeaked out a win! Hopefully we can make some chassis adjustments to get a lot of the hop out of the truck and get back at it!

2011 6.7 Powerstroke getting some replacement parts and preventative maintenance! After the new owner purchased this truck it needed a few things fixed and while we were in the engine bay, this powerstroke got a much needed cp4 disaster kit! I recommend these kits for all 6.7 owners at minimum.
• Glow Plugs
• Clock spring
• EGR Fix
• S&S CP4 disaster kit
• Upper radiator hose

Message to get your ride some preventative maintenance or maybe a little bit of attitude😈

Saturday retune to get this lml buttoned up! After some of the upgrades were done there were some functions needing turned off in the tuning as well as a map sensor adjustment for the bigger turbo. We also found some voltage issues with the map sensor and installed a new map sensor and pigtail. After some testing it should be good to go!
