HPFP low pressure with tune, normal without tune
Has anyone else experienced their high pressure fuel pressure pump dropping off after having a tune applied but normal pressures on the factory tune? With the base tune, the car spits on moderate to heavy throttle. If I put the factory tune back on, the car pulls hard. I have the logs and the maps if anyone can assist.

Do a compare. Open either file, then select compare and open the other file. See if the desired fuel pressures are altered on your base tune.
