My plug cover came from Lee at Fusion Fabrication as did most of the other bling bits. Top work
As I said before the NA tuning is real hard work to get small gains, I enjoyed doing it as I wanted something different and it sounded awesome but given my time again I would probably go ZT as you get more for your money.
I think the pic of the engine in the red car is freak powers car, that is a serious bit of kit but if similar money had been spen on a ZT I expect far greater results would have been achieved (though I suspect he built it for the same reason I did to be different).
