yeah i don't have hondata but i am wanting to order it for my up coming turbo kit but i was looking and wondering do i need to get a boost controller. I am not going to have the software to tune it and i am planning on going with a turbo xs dual stage manual boost controller. I was just wondering if it is needed(recomended) to have a boost controller.

 

if you want to go higher than the waste gate spring, yes, you will need a boost controler.
