Not that it's a big deal either way, but that's BS (for a simple base fuel pressure change)... the computer will immediately begin compensating to the new numbers without a reset, and will probably get there faster without a reset, because it's already learned in, and closer than the default/initial tables in the chip.... just sayin'..
And litlv6, not sure it was clearly stated, but with our turbo cars, the fuel pressure MUST RISE EXACTLY 1:1 with boost.... that's, a 1 lb increase in fp for every 1 lb boost.... it must rise and must be verified to rise.... your previously described 'dipping' fuel pressure is an absolute signal of a failing/inadequate fuel pump.... do not get on the car until this issue is fixed, or you will be changing head gaskets along with the pump....
thanks for the input bmackinnon. is there any type of sound, like a warning as is destroys the head gaskets? or does it just happen. or.......... is that lean out pop i'm describing cause it? thanks for the input and does a bunch of people agree that i should get a denso vs the walbro?
