Just picked up a 2015 SHO with 59k miles, 1 owner never seen winter in Michigan. Amazing car so far. Been modding ST's for a long time now and just starting to dig in to this one. I have a 5 star tune but am getting a lot of hesitation out of it and tough shifts from 1st to 2nd. I have to let off the gas to get the shift to happen when driving aggressively. Swapped out plugs for 1 stage cooler. Helped a little but didn't cure. Ordered new coils so we will see how this plays out.
