So I put in a fuel pressure gauge friday night and then an AirdogII saturday morning. At some point I disconnected the Mass Air Flow sensor to get at something and I found out today that I forgot to reconnect it.
Not a big deal because I didn't get a check engine light and it seemed to run pretty well. However, on sunday I had it dyno'd and got 357rwhp. I thought this number might have been a little low. Does anyone know what kind of effect leaving the sensor unplugged would have on the power being made? I'm tempted to go have it dyno'd again just to see but any thoughts would be appreciated
