I am just about done with the installation of my p600 and had a few fuel questions. I just installed a 255 walbro in tank and have an inline that came with my kit along with the fmu and I wanted to know if I need to run the in line and the fmu or not. My injectors are frpp 42's and it is pullied for 14lbs. I also have a adjustable fpr. Thanks for your help!
Someone please help...
the only way to know for sure is take it to a dyno. You might not need the fmu or the inline but you don't till you try it.
Should I try it without them and see how it does? Thanks
well you can have the fmu on the car an not have the vacuum line to it just incase you a lil lean on the dyno but i think i'd try it first.
YOU WILL NEED IT, I DID! RAN REAL LEAN @ 5K MADE NICE #S BUT COULDNT GO PAST 5K WITHOUT RUNNING LEAN DONT WASTE YOUR TIME, DO IT RIGHT THE FIRST TIME AND BE DONE WITH IT! iF YOU DIDNT NEED IT CONSIDER IT INSURANCE , BUT I WILL BET YOU WILL NEED IT! LET US KNOW!
I finished the install yesterday and only ran it for a few minutes. It is idling high and rough. I havent revved it up b/ it isnt tuned yet. Do you have any tuning suggestions as to fuel pressure and timing? Thanks
FUEL PRESSURE ON MINE IS ABOUT 40# AND TIMING IS STOCK@ 10 DEGREES
