Custom tunes from anyone costs custom dollars. For big turbo there is huge power benifits so dollars to power is well worth it IMO. For this you gain 10-15% over regular ko4. Z can tell you he has over 2 k invested in his tune on his EFR. so things are mot quite as cheap as they first look. Also, know this after the 3 renditions of my build (on of which is back up for sale, baby on the way).
I do like the hybrid idea 350whp all day, but you can get that with a ko4 with a w/m file. You are also closing in on BT prices when all done.
just my 2cents
the new FFE build is up for sale?
