Went from 3% OD to 5% od the AFR dropped almost a full point.What would be the target AFR at WOT?? Timing was at 26* and dropped to 24* at 2500 RPM.

In the immortal words of Monte Smith. You can't burn through anything without fuel. Lean won't hurt anything as long as it doesn't have to much timing. I asked Dick Lahaie once. "how much fuel do you dedicate to cooling the charge?" He answered "none, we burn it all"

So when I increase boost and octane,will it want more timing??

The more boost, the less timing you want. The higher the intake temp, the more timing you take out.

So the add'l octane is just for the increased effective CR?

Put the timing down to 20*

With the ability of changing the timing every 500 RPM should I curve it or flatline it??

You can run it high until it makes boost. My junk has 36 degrees but ramps down as it makes boost.

A real timing curve is 3 dimensional. Timing should increase with rising rpm, and decrease with rising boost. It should be done on a dyno for best results.

This is the what I have been working on and you have given me the key.From zero to 500 rpm is 18* ramping up to 34* @ 1k RPM,,then at 2500 it is ramped to 26* by 3500.Full boost is in by 4k and rises a tad over 6500.
Now to combine the run curve with the boost retard.....

Will the MSD 6al-2 display timing settings on the laptop while on a chassis dyno?

How much are grids now?
On the only iron block aluminum headed blown pump gas Hemi motor I dyno tuned on a DTS engine dyno like 33 degrees all in at 2500 RPM up to 7300 RPM where that motor made peak HP of 924 HP with 7.0 lbs of boost That was with 12% underdrive.
We swapped the pulleys and fuel from CA 91 octane pump swill to 116 race gas and up the overdrive to 13% which ended up making 12 Lbs. of boost at 6500 RPM with 25 degrees total timing , that motor didn't like that much lead at 6500 RPM which made 1027 HP It started to go into detonation and the manifold inlet temps had gone from 130 F to 190 F at 6500 RPM
We stop the test after that pull as the customer car wasn't going to hook 924 HP let alone above 1000 HP on the street

Cab,that had to to have a static CR under 8:1.Now I am at 9:1,4.385 bore and 4.5 stroke @ 3700 lbs.Old fueler heads by Sanchez.
On 92 pump after 5 passes with timing changes only at 1000/1100 DA 26* was the best MPH of 140mph and 9.4.
For idle and cruise I can see staying in the 30 to 32 range.Next time out I will ramp down to 20* by 3500 rpm and get the afr's up into the 12's.

Also want to thank you guys for clearing up my thoughts and putting me back in the right state of mind!
My goal is 8.50 in good air and anywhere in the 8's in the heat.

I think that chart is Procharger bragging that they can give you more usable boost because the Procharger heats the intake charge less than a Roots.
