I'm switching from my map, iat, and gm boost solenoid back over to the stock maf and boost solenoid to pass emissions in the next few days. Can I leave the gm 5 bar map sensor plugged in or can I unplug and use no boost solenoid at all for just the trip to the emissions station? Reason I'm asking is because my stock boost solenoid was not given to me when a shop did the maf to map conversion and tuning for me.
Basically will my stock ecu notice the boost solenoid missing or the gm solenoid being plugged in?

I believe you will need to change the Map sensor back too otherwise the stock ECU will throw a code due to the different calibration settings. I have never tryed this though but I would rather be safe than sorry.

 

Yeah, I got it working. Sean I answered my question. Thanks.
