I need some advice I’m planning on e tuning. buying a full exhaust system thinking Manzo or hks for my 11” mr . Buying a tactrix cable and evo scan. What is required for a tune do I need a boost controller? Y band gauge ? Just trying to get a shopping list together so I can start working on gathering parts.

 

For getting an e-tune, you need a tactrix cable, evoscan, wideband o2 sensor which can be logged by evoscan, and a laptop pc to take a log.
A 3-port ebcs is recommended for building faster boost and more reliable boost control than factory 2-port but it is not mandatory.
External boost controller (hks evc) can build faster boost and more precise control than a 3-port ebcs but a little more expensive and it is not controlled by ecu.　Other parts depend on what you want to do, as you like.
