I will try running the vacuum reading from pre I/C when I bolt on the VF12 this
weekend I have been running it just before the throttle body like the TX3 Manual
says. I dont know why I only get 11psi boost cut. Have tried changing the afm
but never got around to changing the BP26 ECU. I love my 3 inch in every other
way but when you launch with 0boost, have 4psi by 2000, 10psi by 3000 and boost
cut at around 3200 it gets a little frustrating. Flooring it in 2nd from a rolling start
is even worse. I did think the TX3 was the ecu that ran 14psi cut and the GTX
11psi but the drop in power negated its use. Anyway if it can be got around then
yeah the 3" is awesome. Between the VF12 and the Link Ecu in my cupboard
I will get around it eventually.

Question for you Rob the fuel pressure solenoid mounted near the dizzy both
Jim(JynX) and another mate have them removed. What is it ?? Does it switch
on boost to increase the pressure like an electronic rising rate and if removed
what is the effect constant high or low pressure.
