hey guys,
I'm going to be helping a friend upgrade to a frankenturbo from a ko4 on his 99.5 within the next couple weeks. (ko4 is pretty shot) I was wondering what everyone is running for a tune on their AEB cars with a Frankenturbo, and how they like it? I keep hearing good things about the UM 630cc stage 3 tune, but i'm also seeing that some people are getting poor fuel economy with it... anyone have this going on?
Or is a tune change even necessary with that small of a jump in turbo size? He currently has a ko4 setup running a GIAC pc-16 file on it, with all the supporting hardware. Or would he be able to run his pc-16 tune with the FT for a while until he wants to squeeze more power out of it?
