yea u can but a RRFPR is a bit of a crude way of doing it if i was u get it set up on the RR has you must remember a TD04 pushes alot more air at a bar then a ct9.
Its your choice at the end of the day but thats what i would advise
i am running my TD04 just about safely at 0.8 bar with no Emanage or boost controller. Its only a temporary thing though and i wouldnt recommend doing this without other fuelling mods to compensate
if im honest, i wouldnt have got my TD04 put on without my emanage but my CT9 was fooked so didnt really have a choice. although saying that, the car has lasted well over 6 months on this set up. it does run a bit rich but its better than lean and even pops flames when you boot it
