you remove the stock regulator and use the s-fmu as a regulator. i cant help you with the disk thing tho

ok...thanks, also does anyone know were i can get the disks and springs??, im buying it from a fellow member, and he said it has the lagest disk and spring in it.

if your runnning stock injectors i had good luck with the largest disk and dark spring,i had some problems with the 2.72 disk running lean.

Here's a chart to help you determine disc size for the amount of boost and fuel pressure you want to run.

Then use an injector calculator to determine what size injectors u need for your determined amount of fuel pressure.
