Just installed and works great! I would say it has to be you.

Just installed and works great! I would say that due to some small parts and wiring, you need to be at least a decent mechanic to make the transition. It came with a new regulator but it was 50psi and technology. said the ECU would have to be flashed to use it so I had to use my old ECU.

Pros
  • Great for me
Cons
  • Slightly torn
