You guys are funny, that is exactly what we did the first time. Ran it 2-3 pulls, then installed and ran another 2-3 pulls, but like I said something was limiting the results. We smelled something like a burning brakes kind of smell and not a lot changed between the runs. That's why I asked about things like the ECU being reset or the ABS being disabled. The truck had been driven for X amount of time without the Ecu ever being reset, then we disconnected the battery while installing so I thought that might throw it off. Obviously runs on the same day, same weather are the best.
