With an 18LB spring and an AFPR.How did you bump the fuel pressure up to 20?
I'm running the Mr Gasket high flow 180° with a few small holes drilled in it since I'm running TBI style heads on a Vortec block with no bypass.Just curious, what temp of thermostat did you L31maxexpress and playingwithtbi use on your builds?
Is there a reason for the 180? I guess my question is how did you go about picking 180 and not 195 ect.?I'm running the Mr Gasket high flow 180° with a few small holes drilled in it since I'm running TBI style heads on a Vortec block with no bypass.

It helps to keep it a little cooler and I can run a little more timing.Is there a reason for the 180? I guess my question is how did you go about picking 180 and not 195 ect.?
1. Pinching the PCV hose will drop airflow into the engine. Idle speed might decrease. Doesn't mean the PCV system is the problem. Just means that it's a source of combustion air.I ended up pinching the pcv valve hose and BAM she idles normal. No leaks around it either. I imagine the pcv valve iv got let's too much air pass causing what seems like a vacuum leak. I have aftermarket valve covers with 1 1/4 grommet holes.
I thought of adding another breather instead of the pcv valve. I also found an adjustable pcv valve that can be adjusted both for idle and cruise. Pretty cool really. Any insight gentlemen?
The stock one just ain't pretty enough.1. Pinching the PCV hose will drop airflow into the engine. Idle speed might decrease. Doesn't mean the PCV system is the problem. Just means that it's a source of combustion air.
2. I want to know what the IAC is doing to get the idle correct. Is it closing-down to try to compensate for the added air from the PCV? Has anyone dicked with the base idle screw on the TBI?
3. Even if PCV is the problem, why not get a correct PCV valve for your engine instead of screwing the entire system, the bearings, and the environment with an extra breather, or setting fire to a hundred-dollar bill with an "adjustable" PCV valve?
