anyway, if there is someone who knows about this engine and this ecu, or who wants to experiment, I'm available
as far as i know, for that bhp figures you are limited with injectors. there was a video with gtx2867 gen2 with revlimit tune on youtube giu qv.
for stock turbo your gained values not bad, maybe you can get 5-10 hp but turbo is your limit for now.
changing turbo to k04 hybrid or gtx , will limit you about 340bhp, for more than that you will need injectors and lpfp.
