I don't know if this is normal (timing)

I logged getting onto the highway, starting low second gear and stopping the log in fourth.
I am installing the exhaust and MBC tonight, so they were not installed at the time of this log.
Anyways, here are the numbers:

0.16-31 deg
0.30-30 deg
0.44-30 deg
0.58-28 deg
0.72-21 deg
0.86-14 deg
1.00-11 deg
1.16-02 deg
1.30-09 deg
1.44-11 deg
1.59-17 deg
1.73-18 deg
1.86-38 deg
2.00-36 deg
2.17-35 deg
2.31-34 deg
2.45-19 deg
2.59-11 deg
2.73-05 deg

After that it's pretty flat until the next shift, when it jumps up to 30+ degress again.
I guess my question is this: I have read that at WOT you should have a lot less that 38 degrees of timing. Any ideas/suggestions/comments? Thanks.
 
Go back on the hwy and do a full WOT pull in 3rd. From like 2500/3000 on up to 7.
Post that log. Be sure to include RPMs in that as well. What software are you using?
 
I'll do that..I am using pocketlogger for obdii

3rd gear
2340 rpm - 31 deg
2408 rpm - 17 deg
2528 rpm - 08 deg
2612 rpm - 04 deg
2704 rpm - 03 deg
2836 rpm - 04 deg
3064 rpm - 05 deg
3536 rpm - 07 deg
4020 rpm - 07 deg
4528 rpm - 08 deg
5000 rpm - 09 deg
5548 rpm - 13 deg
6000 rpm - 14 deg
6528 rpm - 16 deg
7032 rpm - 18 deg
7788 rpm - 19 deg

It was hard to find a good deserted road, but I just installed my N1 and my new motor mounts, so I found an excuse.
 
Overall it's not too bad. Your timing climbs steadily. You want to watch out for dips in timing, which would reflect knock. Like if you're timing was climbing 7,9,12,8,10,14. The 8 and the 10 would mean you're knocking so you might want to add some fuel.
Looking at your mods it doesn't show you've got an AFC so you can't really change anything anyway. If you do have an AFC I might try leaning it out a little bit from 2600-5000. You could probly get a few more degrees of timing down low.
