[urq] Vacuum limiter

[Bill Bennett]

CIS sucks wind. yeah period, the most basic system from 034-EFI is better 
than any CIS-Hartig system for HP or emissions. goodness!another period!1 
CIS hotter intake temps than 034-EFI 2. higher boost levels with no 
wastegate change when using 034-EFI. 3 faster low RPM responce, with 
034-EFI, no comparision CIS sucks.
