hi there
i did a carb swap on a tbi . i stripped down everything...computer wiring etc..it was a real mess before...now i can see clear
carb is a 650 cfm edelbroke
it start and idle perfectly...start even better than before
before that , i did a compression test ( wet and dry )and all cylinders are good
with a vacuum gauge test
at idle it get 21 but the needle is not steady , it kind move vibrate slightly between 20 and 21
with the help of someome pressing gas pedal and keeping it at 3000rpm range
the needle goes to 23 and vribate a little more between 22 and 23
the truck feel good around the block but when i get on freeway and or up hill . it doesnt have much power
any idee?
also i have a fuel pressure regulator an holley hly-12-881 with a gauge
when engine cold, i start it , pressure is 6psi
engine get warm and it end up just under 5psi
is that normal ?
should i use the vacuum port at the fuel pressure regulator?
