Oh I'm sure you will. Just tune conservatively on that stock bottom end. I just cracked a ringland on 5 lbs. My tune was far from perfect though.

You can get 500. I made 478 rwhp and 492 ft/lbs @ 7 PSI

Turbo: TC78
A/f 10.53
Timing: 9 degrees
Getting valve float...reason for the car being so rich.

^^That's a tiny amount of timing. I ran 15 degrees with no issues at all. I sold my motor and it's still kicking down south of me. Stock bottom end as well.

You should start at atleast 12*. Too little timing can be as bad as too much timing.

There wasn't a point in upping timing if I'm loosing cylinder pressure. But that will be fixed next week. New dyno numbers to come. ....sorry

ps- You usually tune for a/f first...leaving timing down. Once boost and a/f have been achieved then you can bring up timing.

I worried about my rings in my cammed/4.25pullie procharged ws6, im hoping for 500hp on a safe tune
