I've got a nice K&N element filter, airbox fed air through an opened up euro grill and no resonator, FSE PBV, Remus cat-back system.
What in your opinions should be next?
I've a friend with good results on a Superchip and some fine tuning on his XE. I can get one cheap or should I be saving up for something else instead?
I'm not considering TBs at this stage.
