Bulldogger thanks for the info, and i remember you posted this somewhere but i searched and couldnt find it. Please realize i am questioning you in a courteous manner but where are you getting this info from...got a link? To say that the sl55amg pump (Pierburg?) flows 75-80 g/h at idle is assuming that the said manufacturer knows what application its going on and the fuel pressure at the rail at idle...they dont normally post graphs in this manner or have this info. Saying that it supplies 95-100 g/h at redline ASSUMES they know all the other variables like what our redline is and how much boost we are running...what if i can rev to 8000k and am pushing 40psi, there is no way they could provide data based on these variables.

And the difference in correcting your issue from 14.1afr down to 12afr is quite different than correcting my issue of 20+afr down to 12afr. Im glad it worked on your car though. Everything ive read on the DSM forums say the walbro will handle a conservative 500whp minimum, we are nowhere close to that. 2 walbros are said to handle 1000whp. I will gladly spend another $100 and run two walbros in line but i have a hunch the car will still run lean just like it did with one walbro.

I need to know at 60 psi what g/h the pump provides in order to compare it to my Walbro. Thanks again for all your help and pm's.
