I can't find it on ebay mate.
What about the chip and AFR? What I read about Van Aaken it was crappy ECU patch, ppl claim it runned lean on hi revs and practicaly that is not good at all.
Same thing to injections, 105cc on 4 psi may get overloaded (over 80% cycle) and that is way to hell.
I calculated that 14 psi needs almost 250cc's to be save anyway (AFR 11-12)

Have you tested it on rolling road? do you have any usable bhp/TQ records?
