I was under the opinion that the dizzy should be advanced to 10 degrees, one mechanic has told me it's about 9 degree's because they can ping at high revs at 10. What do youse run your timing at with a stock cam ? I was thinking advance it a bit to 11 and run premium fuel.

Interesting, I was adjusting mine the other day. The manual says to put it in diagnositc mode and set 10 degrees. I don't have a stock cam or tune but set at this mine was pinging a bit up hills. Its been running on 95octane . I retarded to around 8degress and it just about fixed it. Going to fill up with 98 next time and see how it goes.

lol, they run 10dec adv from factory, some ppl push upto 14 with 98 octane. ur mechanic doesnt know 5o's.

Straight up go 12 degrees they defiantly like it better. Run 98 and u will have no problem. 14 is prob pushing boundaries.

A knock sensor sounds like a good addition to a free breating 5.0i, mine is running good at 10 degrees but doesn't sound right up top when you give it a thrashing.

inj or carb we talking here?

Injected, do you know much about how the computer controls timing?

U have to bridge the ecu out to set the timing, find some one who knows what to do...

It's been done, sounds a lot better, pulls clean and hard thanks Peter Mac, just need the knock sensor. I don't think advancing it past ten does much anyway on these.
