I bought the Edis but not going to use it, ill drive direct GM coils. I think MS3x has many more features and its more reliable, also i have the electronic boost controller, EGT that makes sense to me to protect the engine, i always wonder some factors when you turbo charge that i never was able to measure because the lack of technology as the real performance of the intercooler (intake temp, air temp and exhaust temp) with all those parameters i believe i am going to be able to develop better the map for my car, and recently i saw in top gear USA the special edition of the 911 and how the car was seriusly affected by the perforance just by the air temp. So for these reason and more makes sense to me the MS3x.
