Hello and preemptively thank you for taking the time to help with this.
I have a 2015 Z51 M7 C7 with an A&A centri, tsp long tubes with an aem wideband added, on it.
I have a DSX baro iat breakout harness. I have their iat sensor and what I believe to be an LS9 3 bar map sensor also from them.
From all the reading I've done about installing these on here, Camaro6, and the corvette forums were on vehicles that went FI and have not been tuned yet.
My car is already tuned and I'm trying to figure out if the iat and baro breakout will affect the tune or can I just plug it in and go?
I know the map sensor will need to be rescaled but to confirm what rescaling does is changes the table the ecu uses for x volts equals x pressure but now x volts equals y pressure.
When the map sensor is rescaled the car shouldn't need to be retuned, correct?
