Not wanting to buy a pair of k04`s till the K03`s die,what mods are recomended to get max power from K03`s and pave the way for K04`s ?
I have RS4 gutted precat downpipes and a milltek single.
I was thinking :-RS4 intercoolers and possibly injectors and fuel pump if it will still run ok with K03`s.
Your thoughts please
1999 S4 bi turbo imola yellow,grey pearl wheels,now with KO4's.
2001 A6 avant 2.5 tdi,the work horse
I'm running between 340 - 350bhp. I have no pre-cats, full de-cat, miltek 3" single, k&n air induction kit, AMD re-map from 5 years ago when they were more reputable , Bailey rdv's.
I'm doing the same as you Imola, waiting for the K03's to die then i want the MRC 400 treatment. I'll change my intercooler's, fuel pump and injector's then aswell. .
