Anyway, I would stick to stock timing for your year model, staying at .8 bar boost. And the mechanic who said he was suprised it made that big of a difference, well um.....well, now you know for sure. Its a big difference. The stock equipment works, and works well for your config. [/B]
But this isn't stock? It's the tuner, not the mechanic, who says I should retard the ignition - on boost, he could care less about stock timing off-boost - to stay safe with the modifications.
'77 S with '78 930 power and a few other things.
