I guess I have maybe 5 or 6,000 boosted miles on the car in two years. I did read online about every 6 month intervals in cleaning the BOV. That's not feasible when we have to remove the bumper. If I run into issues, I will be switching to the Tial option and ditching the Turbosmart.

I'm glad you were able to get your car situated though! Do you have a boost gauge by any chance or did you notice lack of power from the @$$ Dyno?

My car's rear end is more squirrelly when stomping the gas, confirming my power is back. My car has now been supercharged for 3 years and 30k miles. I feel that I have just hit the refinement stage of getting everything where I want it to be.
