I'm noticing occasionally, especially when the engine is cold, that under mild throttle the meth spray will come on at only a few psi of boost and initially spike to full flow on the gauge before falling back to a lower flow level. The spike seems to be followed by a slight bog in the power. Right now I have the 0.6mm jet installed and no restrictor. Threshold is about 1:00 and gain is about 12:00. Should I try a restrictor? Has anyone tried using the MAP control mode instead of IDC on their R56?
