I was reading about the injectors how flow matched would be a lot better especially for TBI. anyone have a brand or place to order flow matched injectors for 5.7L tbi?
I'm also looking for adjustable fp regulator that can be adjusted without taking the unit off.

any recommendations would be appreaciated.

thks

 

You can make your fuel pressure adjustable yourself with about a day's work but if you want an adjustable fuel pressure regulator and flow-matched injectors go to:

i used an aeromotive 1 to 20 lbs with weak spring and 20-? with strong spring. also has vacuum feature if you wish to increase flow at WOT. previously i had to partially disassemble the TB to adjust the screw/spring tension or use shims..www.gmparts direct.com for injectors or ebay. not sure why they need to be matched for flow. seems going into common intake plenum anyway. my intake is single plane. dual plane maybe more important.

 

I think the holley 670 is the only unit that can be adjusted without removal. You can always rig up a tool with a bend in it to slip under there.

 

Check in Jegs catalog. I saw a blue AFPR somewhere with a small **** that stuck down to turn. I bent and cut off a small flat head screwdriver to adjust my while its on the car.
