So I put a new supercharger on and its running good but I scanned it and I have a p1109 code any one have any idea's or anything? I cant figure it out

 

Maybe this old thread might help? https://www.northamericanmotoring.co...bd2-p1109.html

 

Check all your vacuum connections for leaks, esp the hard plugs on the S/C.
​​​​​​Also unplug and replug your throttle body, may just be sticking a little, I've found a unplug and plug can sometimes do the trick.
But it does sound more like a vacuum leak to the MAP sensor, which reads "too" low vacuum, where as the T-MAP reads "too".high levels.

 

I'm having no problems idling or anything it runs good besides for that code so I dont get what's going on

 

Don't trust that it's idling and running smooth, this isn't old school troubleshooting. Mini ECU's are very good at adapting for problems like vacuum leaks and smaller issues, with you never knowing there's a problem, under normal driving.
