I have a Toyota Tacoma with 2uz engine!!
what i want to know is will the factory ecu run with boost?
i heard a rumour it will run up to 8psi is that correct?
or
what mod's do i need to make?
You can install a piggyback ECU on your truck which will allow the stock ECU to run the engine like normal except for when you are in boost then the piggyback will increase fuel and adjust timing according to your custom tune. Check out my video:
