I know this has been done to death but i'd just like advice from someone with experience before buying anything unnecessary.
I've upgraded various parts and have come to the limits of my fuel system:
rev 2 turbo, td-05, power fc, greddy ic, profec b, hks intake and exhaust.
when I installed the PFC it wouldn't start then I read you can increase the duty on the injectors from the commander and then it started and idles and drives even better than before. I went for a spin and all is fine except under load in 3rd or 4th the knock light flashes I immediately pulled back I know this could be detrimental to my pistons but i'm not driving it daily anyway so it's just sitting up.
I bought rev 3 injectors without realising they're not bolt on and I need a bigger fuel rail so this is where i'm at. 300 - 310 safe hp is my goal so do I just get a rail or do I need to get a pump and FPR? anyone with similar mods?
I've spent a fortune on parts and labour and am hoping to get a full respray soon so I really want to save a few quid where I can and I have to get it mapped and tuned aswell and who knows what that will throw up! I know power = €€€€'s but I don't want to buy something I don't actually need
I've used the primer to this point but it's not very clear on fuel system upgrades (section/link missing I think)
wolfkatz rev 2 side feed rail: £280
SARD FPR: £95
Walbro pump: £95 (+ a days labour)
also if anyone can help I need a 3bar map sensor (for sale or where to get the right one?)
