Try letting your ECM learn for a while longer, the performance gets even better and the ECM can learn to compensate for the slight lean condition, takes about 1000 miles. Just an opinion but my car is faster now than when I first did the mod, even if boost levels are slightly lower. What is happening is boost levels are still just as high but they don't stay high as long so you don't see them, we saw this reading boost off the dyno instead of the DIC, we taped into the vacuum lines and used a manual gauge.
