I am all set to put a RB25 turbo, Walbro fuel pump, Turbotech Boost Controller and a Apexi SAFC 2 aiming for 180kw-200kw.
Ive rang a place that was recommended here, and they say that with my piggyback ecu, there will not be much power gains as the ecu will reach boost cut and theres no way this can be removed with the SAFC. This is because the r33 turbo, flowing more air, will reach boost cut at lower boost pressure as opposed to the r32 turbo reach boost cut at higher boost, which makes not much difference in power.
Could someone clear this up as im fairly confused after reading so many threads stating otherwise.
