2 weeks after I bought my car the linkage to open the wastegate broke never allowing it to hold boost, it would go from vacuum to 0psi and never boosted, yours may not be broken since you can boost but it could be a wastegate problem.

Maybe the bypass valve could be bad too, allowing you to not build as much pressure untill higher speeds..? Just a thought.

Mine did similar thing when I first built my car. I was running a stock BOV at the time which was leaking. New BOV corrected the problem.

IC piping leaks or vacuum leaks will also do the same.

More than likely its one of these things. Check BOV first, stockers are worthless.:icon_conf
