In lower RPM's I would see boost spikes of 22-23 psi, it would hold 20 psi through the midrange and taper off to 19 psi at redline. These are all rough figures since I was also trying to steer and stay alive.
I noticed roughly a 1 psi drop down low after going to their FMIC....midrange and top end were the same.
This was on a 2000 AWD engine code. Standard stage 3 not the 3+
APR's kit was:thumbup: I hear that they are going to make one for the FSI 2.0T too...but that would be a couple years out...APR's stuff is definately worth the wait though.
