Every application is different. I think that is key here.
I am running 19* overall timing with meth and am hitting a bit of KR in the 5K range.

I am thinking I am picking up false KR from somewhere. I am in the middle of playing with pulley sizes and timing. I think the KR is somehow coming from the converter engaging.
Every application is different. Spraying meth in pre-compressed air (radix) vs. compressed air (turbo) is very different IMO.

I am running 21* timing on my LQ9 through most of the RPM band, then it backs off to 18* above 5500 RPM - no KR at all. IAT's at the end of the run in the high 130's, 100% water spray. No meth. And those timing numbers are actual spark, not commanded.
Just for comparison sake. And yes I am using the IAT spark correction table (thanks zippy, hope you don't mind if I borrowed a little bit from the tune you sent me....)

spark? (I imagine for you it's the same as when you started, cuz you have it like that
jk)
boost?
With whatever you answer with I am gonna suggest extra timing at the green light to produce a better 60'...but my suggestion isn't gonna be any good for when you cross the 1320, it'll be too high. Hence Zippy's add some timing down low while it's cool and you get away with it. I don't think the arguement is you can't get the same degree from the beginning to the end, I think the debate is, you can get more timing in the beginning for more power but taper it off back to a safer degree once the IAT starts to heat back up.

Last I checked, the IAT's were in the 116 range outta the hole and 145-150 through the traps. The boost is 8.5-9 approx (digital gauge)

It works for me. Glad I could help. How are you liking your Nick Williams 90mm?

I like it so far, but I can't comment on any results directly from the TB, since it went in with the 6.0. The only problem I am having is trying to find the correect clip to hook up the cruise control. There is still a ton of tuning I can do, but I have been putting it off since I am pretty sure that I have a leaking intake manifold gasket. Got a new set at home, just need to find some time install them. I need to make an appt with a Mustang dyno shop and go do all my VE tuning and base spark table tuning in a controlled environment, then I can mess with the spark tables, IAT VE multiplier (it runs lean when hot and rich when cold, go figure....), and IAT spark tables some more out in the "real world".

I'm starting to like your line of thinking! I also like you ideas on trans tuning. (you posted something on that subject a few months ago, and it stuck in my head ever since!) I'm leaving for Bin Ladin land tomorrow, but you'll likely be hearing from me come Sept.

A clean 22* through the traps with the crew cab is pretty impressive IMO. What I meant on your timing at yellow (should of said green) is when you floor it, what are you commanding? WHich if you are saying you are ending at 22* and you already said you finish as you start...that answers my question. Soooooo you don't think you couldn't get a few more horses out of the hole with another 2 degrees? Just the 60'.
And if...a BIG IF you thought you could get another "X" ponies or so out of the hole, just goto the IAT spark correction table and add 2 degrees up to 125*(I don't have the table in front of me or I'd be more specific about the column temp) then from there on up keep it as is since the finish is working for ya.
