I've been reading threads to see the difference between the two, but has anyone tested either or both to know which is better?

I'm wondering if a JB4 with an intake is better than the RC ultimate?

Does anyone know what tunes/upgrades/parts from BMS combined will get the max hp and torque?

I've read RC ultimate is really good on its own but BMS stage 1 or jb4 are better with additional mods? I'm looking to spend no more than $1200 for any mods/tune for an additional 50-60 torque possibly more. Hp should go up as well

Dave,

If you just want a robust solution for sort of stock car ie easy DIY add-ons like air filter and not much more then RCU is a good solution.

If you want something that you can adapt to future mods then JB4 is the way to go.

Lots of threads about this.
RC ultimate and Jb stage 1 are almost identical in terms of power gains and install (JB offers the ability to increase boost if you purchase the BMS data cable , RC does not).

JB4 is a stage 2 tune, it controls boost differently using the Canbus. JB4 can control boost by rpm rather than just adding the same amount of boost across the board. It has the ability to read/delete codes, datalogging and lots of other features.

If you are keeping you car stock Jb stage 1 and RC ultimate are both really good options ( i like the JB because it is more flexible). If you plan on adding more mods JB4 is the only option.

Racechip ultimate boost is upped using the switch settings.
