Default Hydra - 2.5RS Boost Control???

Ok, so I know the hydra has the ability to control boost, but normally through the stock boost control solonoid, right?

Since I'm in an RS, the car was NA to begin with and never had such a device, is there a way I can control boost with the hydra, or am I SOL? It would really be annoying to have to spend another 500-600 on a nice boost controller with solonoid to use for the sole purpose of controlling boost, and I'd probably stick with an MBC if that were the case.

But is there any way to setup my RS to have the Hydra control a boost solonoid so I dont boost 15psi in 2nd, and 17 in 3rd, and 19-21 in 4th and 5th?

When you receive your Element Hydra EMS for the RS we have the system wired to so you can run a boost control solenoid via the Hydra. The new 2.5 Element Hydras have gear based boost control also so you can reduce the boost differences between gears.
