Under heavy load never seen it go past 13. Made 380whp on dyno chasis with my set-up and a/f ratio wot from 4.5 rpm-8.0 is avg. 12.0, almost straight linear line. Car is tuned correctly and runs great on c16.

Your EGT's should be higher than 1300 deg F. You say you are tuned right, how do you know? Your AFR's may be right, but then you need more timing if your EGT's are that low. Heat = expansion = power.
Also, what was discussed earlier, why the bigger piping for the intake pipe to the IC? Vicious had it right, but didn't elaborate on it, the resistance in piping is cumulative. The longer the piping, the more resistance and the smaller the piping, the more resistance. So short, large piping is the best. This is also why people can make huge HP on a stock 1g TB. It is not very long, so the restriction isn't outrageous, but it is still a significant restriction.
