Just s quick question in that I need to confirm what I am thinking.
I have a Bosch hi flow pump (I think it is a 910 unit ) that is to go into a 7M-GTE powered Mk2. The pump will be changed now to cater for future mods such as decent I/C, higher boost etc.
As this pump has a higher flow capacity, if nothing is changed over the stock pump, will i have to reduce the fuel pressure so that I maintain the current fuel delivry for the tune and then modify it alter as I complete the other mods ?
Will I need to increase the size of the fuel return line to prevent higher fuel pressure as there isn't sufficient fuel flow back to the tank due to restriction ?
