ouch man that's no good.. if you still get 25 PSI even with the boost lowered all the way you have some sort of problem preventing your wastegate from opening, or you are creeping.. or a combo of the 2...if you drop the turbo you can port the exhaust side and that will let the wastegate flapper open about 2x more on a 14b.. should flow much beter than stock.. however, it's really hard to creep on a 14b..
