AUII XR8 (220Kw) Mods Help?

[FPV8U]

Hey guys, the AUII XR8 i originally had that now is owned by a good mate is undergoing some Mods..

So far he Kept the standard headers and got a 3" Collector put on them. (Tight *** : )
Single 3" Mandrel Bend Exhaust
Hi-Flow Cats (Made it sound magic!)

Taking to FTG they recommended a BF F6 Airbox, is this worth doing or should we just mod my G&D Airbox thats coming out to throw in his AU?

He tried to get it tuned but for some reason the flash tuner doesn't like his ECU, so were going to get onto capa about that and see what exactly is going on :togo:

So once the Airbox is sorted, what else is worth looking at on the 5.0L Machines?

Maybe Cam & Valve Springs? (With a tune if we can get it working :S)

I think it's still running Standard Coil Packs, Ect how much and how effective would that upgrade be?

Just thinking out loud im not 100% sure what size collector he had put on.

Cam and Valve Springs would be good but do the exhaust first if you're going to do it, because as you know there is no point doing engine work if it cant breathe properly.

The airbox I wouldn't be too concerned about, if your G&D one fits with a bit of work then yeah why not but I wouldn't go out of my way to get one for it.

Ignition Coils PN MSD8241 and should cost no more than $150 ea

Thanks mate, wasn't 100% sure how restrictive the airbox was on the AU's.

The Exhaust is done, as are the cats and the headers are modified to flow better.

I'll get him onto the coils issue and we'll go form there, the things a rocket already gives my 260 a run and then some.
