300hp on a K03 without WMI? What mods and whose map & dyno? I'd be very skeptical of those figures as you need a nigh on perfect setup to get a genuine 300hp
Do you mean me?
My mods are
Cai intake
Autotech fuel pump internals
Milltek full turboback sportscat
Ths intercooler
R8 coilpack
Rev g dv
Its an rtec map thats on it. I had a dyno run at tdi-north there aswell with graph if you want to see the graphs.
Goodluck with car mate. Might be money that people say is wasted but at least you will get some fun out of it. Well worth it.
