1st Dyno Tune Session

[supermariobros]

So after installing some 550's, 190lph pump, and apexi neo I set off to get it tuned at the local dyno. It didn't exactly go as planned (as everything with these cars go), got a decent tune on it and got 221hp/214ft torque at 10psi. Pig rich, started losing power after 4 up to 5. I started making minor changes in that rpm level and did pull after pull with no real apparent changes, still too much fuel. My afr looked like this-----2300rpm 13.4
2400rpm 12.9
2600rpm 12.4
2700rpm 12.4
2800rpm 12.2
2900rpm 12.1
3000rpm 11.9
3100rpm 11.8
3200rpm 11.6
3300rpm 11.3
3400rpm 10.9
3500rpm 10.4
3600rpm 10.1,
and stayed at 10 all the way up. Am i in need of a fpr? I just dont see why im still way too rich. I havent boosted on it since but the car feels alot smoother now. I checked for boost leaks and didnt have any either. My settings are --- hi thr 1k -7, 2k +5, 3k -18, 4k -19, 5k -17, 6k -17, 7k -10. lo thr 1k -4, 2k - 5, 3k -7, 4k -7, 5k -5, 6k - 5, 7k -5. I wasnt too happy with the results but i guess its not that bad on a bad tune. Any input is appreciated.

You need to pull out more fuel from say 3400 up. Do it in small increments until you see some knock, then add 1-2% back in.
