All of the Proformance Unlimited turn-key LS engine packages will include an engine harness and an ECM to allow for full engine control and the best driving characteristics possible. Most other suppliers of turn-key engine packages will use out-of-date MEFI ECM’s and harnesses that do NOT allow the engine to make fueling or timing changes when running, nor will they allow for any needed changes with varying altitude. All of our turn-key engine packages will allow your engine to run and function exactly like a new car straight off of the production line! This will not only help the power output, but it will also help to maximize the fuel mileage! If you choose the Fitech ultimate efi w/trans control this will allow for full control of a GM’s 4-speed overdrive 4L60E, 4L65E, 4L70E, and 4L80E electronically-controlled transmission. The competition’s MEFI ECM and harness does not have this capability.
All of our turn-key engine packages will come standard with the GM Performance aluminum valve covers with a coil pack relocation kit and GM Hot Rod Oil Pan Kit. However, we do offer upgrades for all of these items, which are listed above in the drop-down menus. Let us know if you are looking for an item that is not listed, and we will be glad to provide you with a price! The aluminum coil pack relocation kit allows you to hide the ignition coil packs anywhere you would like under the hood, which provides you with a clean and uncluttered engine bay.
All Proformance Unlimited turn-key engine packages will come standard with a one-year, unlimited-mile warranty as standard! This will require all tuning to be performed by us. We stand behind our work, and when you purchase a Proformance Unlimited engine you are not only buying the parts but also the knowledge, experience, and know-how! We know what works and what is required to complete the installation!
