I'm looking to get to that 200 mark aswel.
I had Spacer and Pop charger with Ztube and got 177rwkw. I now have Extractors and Grounding kit(I don't now if this gives you any more power but when i bought the kit it claimed 5hp) and i'm hoping to get 190rwkw with these new mods. Next is Exhuast and a Dyno Tune. Fingers crossed i get the 200rwkw.
