Sure. Are you using it in FIT mode? Pink top injectors are from b28?

Yes, in FIT mode you have all 6 injectors directly connected to DET3 outputs. (3 injectors per output).
But I do recommend using DET3 in FIT mode. There are just too many variables in the stock ecu changing/correcting the fuel mixture. Only adjusting the MAF signal does not get you very far.
BTW those injectors on a turbo engine are only good for ~250hp anyway, so maybe max 0.3 bar. If you want more power, you need bigger injectors.
In my experience i would say piggyback mode is good for small adjustments on allready working engine and FIT mode for builds like yours.
What size turbo are you using? And can you tell me the code on your ecu? For Non-Vanos engine it should end with 402/403 or 405.
