What's your af correction look like with that maf and injector scaling?

[Freon]

AF correction is fine. It moves around, but generally stays within +/- 10. Keep in mind there is more to it than just the MAF and injector scaling.

Do you have the dual port external wastegate hooked up? On mine, I only have the top port hooked up.

[Freon]

I have played with several setups with 3 and 4 port solenoids.

If you only run one port, it should be the BOTTOM port. The one where positive pressure pushes the port open. The top port pushes the wastegate shut harder. If you only use the top port you are probably going to severely overboost.

You can run it just like a normal single port wastegate with the bottom port and leave the top port open. I've seen a few different setups with a single 3 port setup and a dual port wastegate, but this works fine. It might make your boost "shake" a bit more than using the top port as a sort of air brake.
