Hi,
going to be putting 550s in my00 uk soon,will hopefully be running around 340bhp. Will i need to fit a different fuel reg or will it be ok as it is? I havent yet bought the injectors, so could somone point me in the right direction, where is the best place to buy from £££££

thanks

If 340 is your max goal, then keep your 440's and invest in a fpr to raise fuel pressure slightly, you will be able to fuel for that type of power that way.

You should be running an uprated fuel pump for that type of power and if so its best to get a fpr anyway, there are reports of the classic OE regulators being overpowered by them.

Sorry should of said its already been mapped 310/270. Im now putting a bigger tmic on and was told on the day of mapping the injectors idealy needed changing. I have a fpr that i havent fitted yet.So are you suggesting i fit the fpr and give the injectors a miss?? My main goal is to try and get the torque up..

Thanks

Yep, keep your injectors, invest in a FPR (and a fuel pump if not already) IMO

Your mapper will advise you what to set the fuel pressure to.

Ok will do, i have changed the fuel pump turbo vf28 ported headers etc. Can you give me any ideas how to get the torque up (td05) maybe?

Thanks

More boost will get you more torque, the VF28 is not renowned for it's ability to blow a lot of air at high PRs so I would consider swapping to a TD05 or a VF34.
