Hello,

I have a turbo S2000 and i recently installed a kenne bell boost a pump to increase the voltage on the pump under certain pressure. After the installation the car went on a dyno and when i took the car i noticed that the dash was flickering but not only on idle.

I had a flickering dash problem one and a half year ago but it was happening only on idle and as soon as i replaced the alternator it was cured. Now it happens even while i am cruising.

Today when i turned the key on the walbro pump made a very fast noise like the kenne bell was working even without under certain pressure. I was always listening the pump working when i was turning the key on but never so fast.

Any idea what this can be?

Chris
