General Buick Tech / Re: stupid fuel pressure question
« on: February 23 2021, 08:40:58 PM »
Hello, I'm new to this site and turbo Buicks. I have an 86 T Type with a 60lbs injector turbo tweak combo, 255LPH fuel pump, and adjustable fuel pressure regulator. I cannot get the pressure to go below below 45 lbs with vacuum line off. I have also notice the pressure doesn't climb 1:1 with boost. I have checked all the fuel lines and they are not blocked. Any help appreciated...
