Back to back testing on my car.

Gets tuned in a few weeks with the plazmaman manifold so I will let you know on figures IF all goes to plan. Expecting to get very very close to 700hp.
(Getting more cash together, just bought a F1A procharger kit for my XR8 so things are tight at the moment - my tow car lol)
