Gotchya. I was about to say you must be a tuning wizard if you were at 36* on boost. So on e85 at 13 psi you are at about 23* timing all in. That's sounds about right for a stock 318. I'm hoping to get around 26* with meth at full boost. I have a half filled block, ARP main studs with a girdle. I hope it'll hold.
