This LML twin kit was designed and engineered in conjunction with DuramaxTuner. The kit was built to provide an OEM level fit and finish. The kit allows LML owners to run power levels up to 650 RWHP without compromising driveability, reliability, emissions system performance, or ride comfort. This kit is a favorite amongst the Duramaxtuner and WCfab staff for the way it effortlessly delivers mountains of torque without any extra noise, smoke, or less refined attributes of the diesel performance aftermarket. The Duramaxtuner team have put 40K+ miles on this kit towing heavy, running grades, racing, running in bad weather and at altitude. The truck hasn't skipped a beat. The drivers prefer it because after 4 hours on the highway it's still quiet and cruises contently in overdrive.
If you're operating this kit at 520 RWHP or less you can simply install this kit, tune the truck and go. Regen intervals will be longer than stock, and you can run the maximum effort tune under most any operating condition. There's enough air to keep the engine cool indefinately.
Running the kit at 650RWHP we recommend transmission upgrades, a 10 bar MAP sensor, 10mm CP4 high pressure pump, and a 2700 bar Fuel pressure sensor. We've found this is the useable limit of the stock injector.
If you have any questions about its performance or installation, please call. We're happy to help!
