Review on ๐Ÿ”ง GrimmSpeed 070002 Boost Controller - Enhanced Black - Manual Control for Ultimate Performance by Darrin Lucas

Revainrating 5 out of 5

So easy to tune Engines and engine parts

I installed one of these on my 1990 RX7 Turbo II. Unlike all other manual boost controllers that I like. Has arrows and + and - at the top, count the clicks and read the scale with numbers to set the boost pressure. It is really that easy. When I pulled onto the track the other day, popped the hood up and shifted the thrust up a few gears before heading home, I re-did it for the ride. Works well, definitely recommend.

Pros
  • Turbocharger and supercharger parts
Cons
  • No automatic
