I'm going to have to call him to find out, but I would rather have an adjustable FPR anyhow I think...
I just checked my manifest, the chip sold through HRE to you on 6/18 was indeed the DME III chip, requiring 3.0 bar FPR. You can indeed use an adjustable, but when you set your pressure (43-45psi) do so with the vacuum line disconnected and plugged. If you set it with the line connected you will end up with too much pressure, as the vacuum drops the pressure. Likewise, under boost, that line raises the pressure. That is why they are called rising rate FPRs. Make sure the adjustable you buy is indeed rising rate. If it does not have a vacuum line nipple on it, don't use it because it is static and will not fuel properly under boost. The standard 3.0Bar Bosch unit is what I recommend for most people, it's plug and play.

Regards,
Russell
