I'm using mid during the winter due to our winter mix that this area recieves. I have definately noticed that it takes almost a full two tanks for the ecm to completely learn/ and get the full benifits of a change in octane. My only reason for switching is that I think the winter mid is probably a little more comparible to the summer 87.

Thanks again, and I just saw the pics. Nice, not too ricey! I'll keep that tip in mind.

 

I got a ride in Karens HHR the other day she had the IMCO and it was loud when the windows where down but you couldent even hear it that much when the windows where up, She also had the CGS , dident hear any nosie from it. Most was from the IMCO. Hope this helps.

 

It is not loud,,,,,,,It Purrs!
It was Growling when the foot was on the floor bd, to show you and your Dad what it could do!
Your Dad surrived the ride!
