AYC Electrical issue

Got an Evo 7 with both AYC & ACD, the car was previously rewired with a complete wiring loom.
AYC pump seems to kick in real soon while in straight line, at minimal throttle rather than full throttle, and it's affecting the car electricity as I see the dash lights dim down for moment when the pump operates! I'm also suspecting that it might be affecting the fuel pump performance. When I disconnect the AYC pump the problem is gone & the car performers better!

Should the AYC pump operate while in straight line at minimal throttle?
I have Evoscan & I can log the AYC ECU, but I'm not sure to look for!
