RPMs not dropping quickly with SE StgIV
I have a 2012 SG with a SE StgIV package. It runs great but from day one the rpm has been slow to drop back down to idle. I've questioned my dealer service guy and he said it was normal with high compression. I had Dyno tuned at 1000 miles 108/112 with no dips in the curve. Any suggestions ???
