how much boost are you running and what turbo? If you are running a k14 intercooled to 20psi, I would run it around .90 to .95 mm tops. I like .94mm the best for my setup. Less timing seems like more with his pumps. That is the info I have on the 1.6 stuff, but if the aaz has less timing to begin with you may just go .05-.10 mm less than what stock is.
Also, you could just get ahold of him and ask come Monday
