I also took mine off. I have headers, HF cats, CAI with scoop, and Bo White Ported TB. Car was running fine with no codes. I put the VTC on and took one short drive...wow, what a blast! It makes a very noticeable change in the pedal! But a few days later I went for a longer drive. It was fine most of the drive, but suddenly it kept throwing me into reduced power mode. DTC P1516. This means ECU is reading different actual throttle position than pedal position. This tells me the feedback from the VTC is confusing the ECM. I took the VTC out and have driven the car several times with no problem. I have had the battery unhooked for a couple days. Going to install the VTC and then hook up battery and reprogram the VTC. Hoping that works because I do want to use it. If it goes into limp mode again, I will leave it off the car.
For those saying it does nothing, you just push the pedal, you are flat wrong. Don't ever judge until you try it yourself. I was skeptical... But was pleasantly surprised! Hoping my ECM reset works and I can use it.
