I'm a dope. Didn't see it under tuning/firmware. Do the alpha maps move to stable at some point after testing for awhile?

Yes, the beta branch is pretty stable just be aware that the basic maps can change update to update especially when they are done early in the lifecycle.

Has everyone that installed the JB4 had a positive gain in power/torque?
On any of the Map settings is everyone getting poitive gains, For roughly a 1000$ is it a noticable increase.
I am a little on the fence, but want some HP/Trq increase. Bang for the buck

Thanks In advance

It can go as far as you want and can be resold in the future. Is a flash better? Yes but the options are slim. On my 6mt I threw it on map2 and immediately felt quite the difference.

Sport+. My map with e20 (also for stock pull). Peak boost 23.8 psi
This is a pretty low tuned map theres faster ones by around half second

I guess I'm coming late to the party, but....

Did you figured out how to overcome the tq-limiter said to be found in Sport+ and forcing JB4 users to drive in Eco to maximize performance?

This fix is in alpha stage I think as moproblems mentioned in a post above.

Mike which flex kit your planning on running? Can you use BM3 flex kit with JB4 or does it have to be JB4 version of the kit.

Whats your experience on Map 3? Did you use 93 fuel?

I'll be running the Fuel-it kit since that's what BMS recommends.

Im not sure if the PTF kit would work with the Jb4, but I don't think so
