The Aces EFI system installed in this vehicle is producing inconsistent results. Four consecutive dyno pulls yielded significantly different horsepower readings, with no modifications made between runs. Additionally, the idle counts varied substantially. Despite my efforts to contact technical support, including extended hold times and unresponsive live chat, the issue remains unresolved. In my experience, alternative EFI systems like Holley, FuelTech, Motech, Link ECU,Haltech, Emtron and factory ecu tuned by hp tuners have proven to be more reliable and consistent, and I strongly recommend considering these options. If you call or message us and a few other tuners I know in the area we are all going to tell you no, we won't tune your aces efi. We dont want put out a bad tune due to an inconsistent ecu.
