I need to know the part number and price of the GM adjustable fuel pressure regulator that all you guys talk about.. i figure it would be a good idea since I am getting a new cam and she is sputtering at high rpm's already.. i can imagine what will happen with a new cam... it will just fall on its face after 4,500... right now at about 4,500 to 5,000 it feels like one cylinder goes half dead... not a big difference but i can tell she is missing... the only idea i have is that its leaning out bad...

 

go to the tech articles where you can learn how to makes your stock fuel pressure regulator adjustable. I did it to mine a month ago and it was really easy, just follow the instructions and you will be fine.

 

That or try a search of this forum......

 

Turbo City
Turbo City makes an adjustable fuel pressure regulator for TBI vehciles. I have one and its pretty nice. But like everyone said, apparently u can make ur own if u check out the tech articles on the main page. I got mine used for $45.00

 

Try your local GM Dealer... "Yellow Pages"

 

Maybe he's talking about the vacume referenced adjustable FPR from GM. PN 17113186 . I think it was about $45.
