Nope... and the issues your experiencing are due to the butterfly valves opening and closing when your DME is not expecting it to.
IMHO... 3 stage manifold is a waste. It would probably work better if you got a 330i DME or a tune with a 330i program...
or... put back your wide-open 325i manifold, because i don't know about everyone else but I only race in the higher rpms with a wide-open throttle.
