I have a 2011 Mustang Gt with Roush TVS, and I got an after market mail order tune last month.
Not sure if this is an issue but I have noticed when getting ready to come to a stop when I put the car into neutral it takes a little bit for the RPM to go from 2k to 800 RPM, and even takes almost a full minute sometimes to get to 800 RPM. I also notice sometimes when I get to a complete stop the car goes from 800 to 2k RPM, and then slowly goes back down to 800 rpm.
I have done idle relearn process a couple times, and waited to see if after couple of weeks of driving if it would go away.
So is it an issue, or not?
Thanks
