"The instructions should read: Humanly impossible to install on a Tundra. However, with a few temporary relocations of nearby equipment (air box and fuse box) I was able to reach the ECU plugs. The instructions should include notes on this. Before installation, I made several fuel mileage checks. I was running about 16 mpg hwy and 14 mpg average. Once installed, the power was noticeably more by throttle feel in the open setting, but I resisted the acceleration until I could get some solid fuel runs. In the closed setting, this truck is ready for the brackets or a bog race. The power is incredible (includes K&N and Gibson Exhaust). My economy increased to 20 mpg hwy and 16 1/2 average. I am well pleased with the UniChip." —Jon D from Lakeland , FL bought an Unichip Performance Chip for a 2008 Toyota Tundra.
