I will be installing a Magnuson SC. The VF Tuner that came with it gives instructions to update the ECM to the latest Toyota calibration. I am not going to use the VF Tuner but instead will be using HP Tuner. What I want to know is, do I also have to have the latest ECM calibration update to use HP Tuner.
You do know that VF tuner is more specific to Toyota than HPT right? Maybe gather some research and find what works best first?
