FPR is not a must, i ran a vf28 with 440cc injectors decat, fmic, standard exhaust mani, and a cheap air filter and a simtek because there was nothing you could do with my ECU as mine is a 98, at 333bhp.
Then moved onto 550cc with a walbro 255 and a td05 18g at 351bhp.
Then got bored and moved on from that
