Depends how you want it to function?
The stock hi/lo It's just a fixed position bleed valve, so if you pipe it to alter the boost whilst the controller is still trying to control it, then it will have a fit.
If you get a boost controller that doesn't have closed loop control, then it will be better, but a waste of time imo.
I will be honest, once you fit an exhaust with decat and uprated adjustable actuator the hi/lo is pretty useless anyway.
You would be better off using the hi/lo function to change between settings on your ebc. It's on my to do list to have a go doing it.
