Thanks shiv

set the"start boost in 20% or 30%?
or set the overboost limit at 12or13?

You may want to get in contact with Shiv for some advice on why you were running a little lean for a while, then went very rich before leveling off. Your timing is still terrible, but that has a lot to do with you changing the Ignition Correction and because of the poor quality of your fuel.

thanks
but I can't change the timing....
