Nice.
Going to just enjoy it like that for a while?
Before getting antsy for more tuning, take it to a drag strip or dyno. IMOyou will have a good baseline for both street driving and give you some information about for maximum performance.
While a dyno cost more than a drag strip, its not more if you added the cost of a datalogger and all the time needed for learning, etc.
To make the chassis dyno worth it,
a) it has to have an WBO2 AFR sniffer. Whether its in the tailpipe or a bung isn't too important.
b) they have to provide you the log files and a way to read them.
Otherwise dragstrip is cheaper and often more fun.
Here's are some results from my previous 340.

Because of the way Dynojets are built, using speed instead of engine rpm reflects more directly the data collected and how it calculates power.
Anyway the reason for posting the screenshot is the AFR.
The first run was with the 76/80 main jets. The vacuum secondary opening is so rich it causes a dramatic drop in AFR and a blip in the HP curve.
This was not quite as obvious in real time because the scale wasn't expanded the way it is in the screen shot above.
The AFR on the other two runs is relatively flat. That suggests the jetting and main air bleeds have good relationship.
