Last night I was testing out the differences in sequential and TTC. In sequential, I was hitting 20psi in 3rd and holding. In TTC, it would spike 20psi and fall immediately to 16psi to redline. What would cause this difference? The eTTC switch simulates the ECU's signal to open the actuators, so how could there be a difference there? I hope someone has some input. I like driving in TTC, but sequential pulls and boosts a whole lot harder.
