Maybe so...but my plan is to leave the car pretty much alone until warranty expires. Then, I may do some playing.

you are going to be waiting a long time for your warranty to expire. it's good for 5yr/60,000 miles powertrain


the Bullitt dual fuel maps is pretty effective. When I bought mine, it had 87 octane in there. I ran that crap out and filled with 92 octane...immediate difference.

Me too...running premium now. Can notice the difference. Nice to know I can run regular tho...say I plan a long drive...just a trip where no extra go wanted. BTW, I seem to be having problems posting on the Bullitt site. They have a waiting period or something? I log in, and it says I'm there, but I "may NOT" make posts. About to give up. Probably my bad, since I'm a computer illiterate.

(edit update) I'm now on the Bullitt site...thanks for the heads up.
