Looking for 3500k to 4000rpm full boost. A/Rs 0.96, 1.00,1.15 or higher?
Two walbro fuel pumps with rewiring.should be enough?

duties are close to 99% to 100%. i was scared. my tuner told me that you can run stock injectors close to 100% no problem. but he said aftermarket injectors like sard could only be run at 90% duty cycle. I use my car at 12psi on the street and 15psi with 100% duty cycle on the strip. So i don't run them 100% all day. Probably 2 nights a month at most.
