Original problem, installed 720 and car ran lean on low boost, don't thnk i had enought fuel flow to support 2 720s and 2 1600s. Probably need a AFR.



Second problem,

Swap back to 550 primaries. Car hesistted on vaccum and idle. Now this one took me a day to figure out.



Care to guess what it was??

I feel so dumb

 

did you have the injectors mixxed up?

FPR not connected to vacuum source?

mike
