I finally got my car mapped fully today. Im running a fully forged 4efte with a gt28 race tech set up. Also has a zisco fuel rail 550cc injectors, zisco plenum intake manifold, fmic etc etc. It made 253bhp at 1.6 bar. I guess putting a bit more boost through it would get me more but what sort of boost is plausible? 2.0bar pushing it? I'll get a photo of the graph up tonight.
