This Ram was light work with our custom Dyno tune on both ecu and tcu for the 68RFE. Very solid gains with room to grow but customer was just chasing that mid range increase for his fresh new exhaust.

Modified take a dive into giving use some basics, about common rail diesel tuning 💻📈 While showing off some easily had Gains on this Dmax from our custom tune 💁🏻‍♂️ It’s not all about making the most power. More about what parts are on the vehicle and what’s there limit or limitations. Efficiency is KEY, beyond that is exactly that INEFFICIENT. Diminishing returns. Modified diesel have always taken a strict approach to how we achieve the outstanding results and gains we get from our custom tuning on each vehicle. Power and torque you can enjoy, with efficiency at the bowser and reliability the highest priority 🫡

Toyota put us in work with the 200series. A twin turbo V8 common rail diesel that’s slow, unresponsive, not that great on fuel, tow drivability lacking. Our SIGNATURE PACKAGE sorts all of the above 💪🏼

The old Td42t forklift moda in for a tune. While we do packages for these ranging from very basic tune and boost t, all the way through to complete turbo / pump / FMIC upgrades that range from 200hp to 300hp, all we did here was rip some shims and watch the clutch say get F$& then dial it in some more. End result was decent for a clutch hanging on for dear life and a turbo that’s at the end of its efficiency range. Located Port Kennedy WA, we tune plenty of mechanical fuel pumps even the old overrated forklift modas 😂
