Propsort 52mm Evo Electrical Boost Controller Gauge

Save your money. This thing will give you a quick boost spike and that's it.... uncontrollable boost. Not good for your engine... if you can decipher the half baked attempt at the instruction sheet, then you should be a Soviet code breaker..

When i went to dyno the car it couldnt even handle 20psi. it would hit 20psi and freak out and revert back to my waste gate psi. then it would spike to 20 psi and freak out and back down to 15psi. However the boost gauge was accurate +/- 0.3 from the dyno reader
