Had appt last week at the Dealer for updated valve cover and pcv,the service advisor informs me will have to come back due to wrong part,spoke with the senior tech which is a buddy of mine and informed him that the car seems to run sluggish,he said while your here lets due an oil change and update your computer,told him the tune is loaded and he said next time you come we will update the computer,when i left the dealer noticed the radio was off and he resetted the dasboard settings,what surprised me was the car seems faster and the shiftt point are firmer,like when getting a tune for the first time,any suggestions? did have the tuner on the seat but not the 2-bar to put it back to stock.
