Wow, thats a big increase! Did you add boost, or is this just timing increases?

Duh!!! a little more info on my part might help..sorry...

yeah, he increased fuel,timing,maps,boost....from a stock of 14.5 psi to 22psi....and av gas...but , all this was on a stock motor..no forged pistons, etc....here's a video also.. and the new bigbore pistons and sleeves..still a 9:1 motor..

I dont think the smaller Autometer o2 gauge was hooked up. Mine does the same thing, floats at around 15:1 when its unplugged. I think the bigger one above the boost gauge was the actual AFR...

You are correct...the smaller one was not used. Incase you missed the video of the car at glamis, here it is..
