How much power should I expect from upgraded cams and jba headers w non catted y pipe? 2013 Ford F-150 5.0. And what other mods suggested?

It has a resonator delete super 44 series dual exhaust, aftermarket air intake and it is tuned. Currently pushing 385 hp and 385 torque at peak rpms on the dyno on e85 . Also other then cams and headers w y pipe what mods would you guys suggest next for improved performance!

Hyper-Tech chip, high output fuel pump, high flow injectors. That keeps you out of going inside the engine.
With what you have done the headers are really a big bang for the buck. More air in faster means more air has to get out faster.
385/385 is good for what is basically a stock engine, especially running swill 85.
The hyper tech chip changes the parameters in the ECM. One of the changes is bumping timing advanced as much as it can take at the time. Running swill will cause pre-detonation then.
Wanna fly ya gotta buy.
