1G 1g N/T FPR and Walbro 255?

[matt98eclipse]

Hey guys my walbro 255 fuel pump should be in the mail tomorrow!! Would it be ok to run a 1g N/T fpr and the walbro fuel pump???

I will be tuning with the MAFT and i do have a datalogger

Youre more than likely going to overrun the FPR. A simple search could have told you that.

it will overrun, you can try to tune it but it will not be very stable on the low rpm side. some say that it is sometimes. It seemed stable on mine but it wasn't. besides, your already trying to fool the ecu using a piggyback device and now it sees a really rich low rpm and not as much at the higher end. makes for a not to reliable tune if you ask me. then again i was trying to use the stock fpr, 255 pump and 660 injectors with a maf-t. not a very good combo. DS-Map and AFPR here i come

i have to take the pump back out cause the damn o-ring isn't sealing right. hard to start after it sits a while. kind of a pain cause the tip isn't as long as the stocker

Sorry man i was searching right before i posted and i really coudn't find the right answer. Even if i was to lean it out with the maft? Im only planning on running about 18 pounds of boost.

18lbs? can you do that without any tuning device?

Im tuning with a maft and a datalogger.
