Fuel pressure question....

[Pitbozz]

I am still trying to get my car lined out and have been trying to get rid of my BLM gremlins. It was reading high and I did the engine cleaner trick to find any leaks. The bolts had backed off a little on the downpipe and tightening them got the BLM's in the ball park. To make it run leaner, do you increase or decrease fuel pressure?

Decrease the fuel pressure to lean it out. Increase it to richen it up.

What were/are your BLM's at? A high BLM reading indicates a lean condition.

Thanks turbotaone.

Kenne.....When the pipe was loose they were running upwards of 150 & 160. Now they are around the 120's. I know 128 is perfect, but my 02's are in the mid 800's and was gonna' lean it out a little.
