![]() Now, the question at hand, what can you benefit from the aftermarket? How about added power to get you over that 300 rear wheel horsepower mark? How about even better fuel economy or added lift for larger tire fitment? If you are unsure of what parts are right for you, don't hesitate to give us a call and we would be happy to assist. The end result is even lower overall emissions. ago Which version of 6. ![]() I can get 27 with my stock 6.6 on country highways. ago Keep your foot out of it and should be able to see 30s. An electronically controlled valve activates the low-pressure EGR system, the engine burns exhaust gases that have already passed through the filter. Besides the couple pedal controllers there is no real available marketed tuning for the 3.0 duramax CoyoteDown 1 yr. Exhaust gases are drawn from after the diesel particulate filter and re-introduced after the compressor inlet. This improves efficiency and performance. This engine features a low pressure EGR system that supplements the existing high-pressure system. ![]() Improvements to the emissions system have been done as well. Get The LM2 Two Tune Pack Tuning For LM2 3. Many of the specifications of this 3.0L are quite similar to that of the larger displacement diesels, featuring such components as a variable geometry turbo (VGT), high pressure, common rail fuel system, water-to-air intercooler, 10 speed automatic transmission (Hydra-Matic 10L80), and many other items. Now this is pretty respectable for a half ton truck, but where the payoff really lies is in the rated 26 highway MPG's. The LM2 Duramax engine features an inline, six cylinder arrangement boasting 277 horsepower and 460 foot pounds of torque. Yes, we understand the diesel LUV was truly Chevy's first go, but again, we're talking about late model vehicles. Adding a tuner and intake to the Duramax will easily add 30-50whp while also providing improvements to fuel economy. Additionally, performance modifications will be significantly cheaper per horsepower. 2016 - 2022 Canyon/Colorado 2.8L Duramaxįor 2020, GM made some huge waves in the light duty diesel market by introducing their first late model, inline diesel engine in a 1/ pickup. Since the Duramax is a turbocharged engine it is going to have better tuning potential than the 5.3L.It's complemented by a stiffness-enhancing aluminum lower crankcase extension attached to the main bearing caps. A deep-skirt block design, where the block casting extends below the crankshaft centerline, also contributes to the engine's stiffness and refinement. GM said at the time, "There are seven nodular iron main bearing caps that help ensure the block's strength under those high combustion pressures while also enabling accurate location of the rotating assembly. add fuel at higher TPS settings, use 50/50 timing calc, and you will need a boost controller to add boost on an LB7. Engineers chose a lightweight cast-aluminum alloy block and cylinder head for weight reduction and added durable material for components such as the iron cylinder liners, forged-steel crankshaft and connecting rods, and blended silicon/aluminum pistons. An exhaust brake allowed for engine compression to slow the vehicle to reduce brake use while in tow/haul mode, a particularly useful feature when traveling downhill. Another focus was minimizing noise and vibration. So they added advanced technology including a stop /start feature to boost fuel economy, performance, and efficiency. The Duramax engineers had a blank slate from which to develop the new 3.0-liter inline-six.
