siadam is dead on, rewire that pos. when i go turbo big power i am going to also. read the voltage at the pump with your kbap off, i bet its down around 10-12 at best woith the car running. rewire it and you should see near 14 at idle. just the voltage increase there means more flow. then add the kbap and you wont have to crank it as high to get same performance, and you may extend the life of that walbro.

To be honest i do not know cause it was installed by a professional but i am sure it was connected as per BAP intructions. For sure there is no wiring straight from the battery.

This is true like we talked before. The voltage power on the walbro drops a lot if it is not connected straight from the battery. You might be right and do not have to crank it so much with the wiring straight from the battery although i cannot figure why with my basic electronic knowledge. The BAP supposed to multiply the input voltage according to the crank regulator. So if lets say for example you crank it at 20% this perscentage for the BAP means output voltage of 15Volts (the numbers are erelevant and not actual). This output voltage must be the same independently if the input is 10Volts or 14Volts if you have rewire it straight from the battery. If what i am saying is not true then for sure you are right and if i rewire it i would not have to crank it that much.

I think your mis-understanding.

Try reading over the instructions yourself, and reviewing some threads here and I think it may help clarify for you.
