I just bought a new 2015 without performance package, at about ~500 miles right now. I'm not sure yet how my dealership feels about getting a performance tune, but I'll probably be putting one on before 10,000 miles. I've been reading a lot to try to see what I need to try to keep the car running long term (hoping to keep it as a DD for at least 6 years.)
Seems like oil catch cans and some kind of transmission cooler are the main things, is that advice still current for the 2015 model?
Also does anyone know if 91 pure is better or worse than 93 with 10% ethanol? Will it make a difference to which tune I need to get?
Finally, how feasible is it to get this car down to 0-60 in ~4.0 seconds? From what I've read it looks like I can expect it to go down to around 4.5 seconds or so with a tune, would love to try to get it to the 4.0 second mark though
PS: The car is pretty jerky around 10-15 mph when I'm light on the pedal (and I noticed it jerking pretty hard around 40mph as well once), going to take it to the dealership service so they can check it out but does that sound like the adaptive shifting just learning bad habits from me flooring it to the speed limit too often? (I've been mostly light footed since it's in the break in but I couldn't resist a bit of fun.)
I'm not very car-fluent so hopefully I've described that with some kind of accuracy. Thanks for reading!
