I run mine banked, (all 4 fire at the same time)

I run two banks of four. The second set are slowly phased in as boost and revs rise.

Banked is supposed to give better throttle response than sequential as there is always fuel waiting behind the valve.

I believe sequential was originally designed for modern cars to help with emmision laws.

My MBE ECU is capable of running upto 16 sequential injectors if needed, before anyone asks.

Steve Broughton at SB Developments advised me to run this setup as he has tested both setups on his race cars and datalogged the results.

He found that banked gave the best results.

Would be interested to know what other people use and why?
