Vortech FMU/fuel question for 8psi
 

Have a 1.6 with a Greddy and recently built up an intercooler. I have boost at 6psi but wanting to go to 8psi. Picked up a set of 1.8 injectors but looking for affordable way to get more/appropriate fuel pressure from the Vortech FMU. Braineack's awesome thread does have almost everything I need to know, except specifics on a recalibration kit. Can anyone offer some help on this?

"The Vortech FMU (standard on the GReddy kit) works in the same principal however the amount of fuel pressure rise is determined by a disc and cannot be changed on the fly. Recalibration kits can be bought for cheap however they require the disassembly of the unit to change the ratio."

Tips on what to order and disassembly of the unit would be massively appreciated. Thanks.
