Zas,
Are you using stock fuel reg? If so, you do not need the walbro fuel pump for under 200rwkw. Put back your stock fuel pump with your stock fuel regulator and tune it. You will get the power everyone is getting for that setup. If you want to go more then 200rwkw, then get your turbo hiflow, walbro fuel pump with stock fuel reg and a proper tune, you will be able to get close to 230rwkw.
