IIRC, the fuel pressure for the 2.1L WBX is 29psi w/vacuum and 34psi or so
w/o vacuum using the stock injectors. The fuel injection manual that came
with my TiiCo kit says the fuel pressure should be 36psi (2.5 bar) w/vacuum
and 43.5psi (3 bar) w/o vacuum, but the TiiCo instructions say to re-use
the Vanagon FPR. The difference between the systems, however, is that the
fuel injection manual was written based on Golf/Jetta injectors/FPR, and I
believe the Vanagon injectors don't have the same flow rate.

In the Motronic system, would this smaller injector size call for the
vanagon fuel pressure readings (29/34psi), the Golf/Jetta fuel pressure
readings (36/43psi), or something even higher?
