Tuning electronics (turbo)

I’m not up to date on the atv tuning electronics etc. I made a call to comp turbo recommendation on a turbo they can’t custom build me one that small, so they recommended a Garrett Gt1241 internally wastegated unit. What’s out there for tuning electronics I would need some thing with a map sensor to change the timing and fuel curve. Basic boost For every 1psi of boost add 1lbs of fuel and pull 1 degree of timing.
I’m just trying to figure out what I’m going to have in boost vs high compression NA motor.
Thanks in advance
