not bad, could use some more timing though. Aim for about 18 degrees at 7K. Also, if you are on a pocketlooger, don't log so many meaningless things at once. keep it to rpm, timing, and maybe airflow if you really must know it.
 
Thanks I can't go any higher in RPM because its an auto :cry: thanks for the logging tips.

Looks like you could use a little more timing, either with better tuning or more injector.

You can't. What do your fuel trims look like? It may be possible you are overrunning your FPR and causing the injectors to lean out on the top end from flow decreasing. It's also possible that your stock SMIC is getting heat soaked.
