need fuel pump advice

Post by tvsn94 » Sun Mar 06, 2016 6:21 pm

I have just installed 60lb Siemens inj . this is a new motor but same spec's still 302 cuin.11lbs boost. anyway, at WOT in 3rd while tuning i am leaning out between 4900- 6000. I am sure i am out of fuel pump/system. it is all stock except a Walbro 255.
It appears that I only need a bit more, whats the simplest way to get enough to support 650-700. I am sure somebody has found this bandaid already. any suggestions are welcomed

no worries your nowhere near 650-700

most likely your tune is to blame, go max out arcwotcor to 1.992 and she should be rich up top
