I installed a Walbro 255 lph intank pump last night...The car ran fine at first but then all of a sudden when I went to go WOT the car would bog pretty bad and my rpms wouldnt move...Eventually the car died out...When I went to start up again it was real rough and wouldnt start.....If I let the car sit there for some time, it would start up but eventually stall out again....

Im thinking I flooded the motor with fuel...i figured the stock regulator would be able to handle the new pump, but I was also thinking maybe I need to change some numbers in the emanage values to let the emanage know there is a much larger pump in there....

Any ideas guys?

 

the emanage is not going to require you to change anything with the larger pump...there is probably a problem with one of the injecters pulsing higher than expected...I had that problem when I first put on the Greddy kit. You need to check the resistance of each injector....also I wouldnt adjust any of the emanage unless you are on a dyno. I did that one time and messed up some things...the car ran like hell....I would just check the injectors.....the problem probably lies there.

 

kinda sounds like your running rich.. change your spark plugs and try to lean it out a bit...
