Alex, did u get my PM regarding the LPFP ?

fuscobal:
Forgot to come back with the results. The TT-RS pump install went fine with a minor mod to the floating mechanism as it was touching the wall of the tank (I suppose this was the cause for the fuel readings most guys have). Fuel reading is ok for me. After the install, car pulls much stronger but i see no more than 3.6-3.8bar although the requested is 4.5bar. Duty cycle is only 50-60% as opposed to 90-100% for the oem pump, which shows pump has plenty of capacity left but doesn't use it. May it be the oem controller limiting it ?

Oem controller or your mapping, or both. I would have though.  I have the TTRS pump too

Hey Matey

what was the minor mod to the floating mechanism? Did you remove the one from the old pump to fit to the new pump?
Thanks
