I’m new to stand alone.

im going to get the car tuned tomorrow. I was looking at the ECU and it read that the internal MAP sensor only reads up to 22PSI.

if I’m running 26 PSI boost, do I still need to connect the the vacuum host to it?

 

Im not an expert either but i was told the Map sensor on the Haltech can be blocked off and you can use the omni 4 bar or whatever other map sensor you have on the car.
