Do you want to tune the engine and transmission? or just the engine side of things?

I want to open the ECM to be tuned by my speed shop Dont know what to choose in the website .. It has Jasper tune i guess for transmission.. It say controller..
If you just want to tune the ecm you'll need an MPVI3, E90 unlock and credits. https://www.hptuners.com/product/gm-...-ecm-services/
