I got my FiST less than a week ago and a few days ago i noticed the car drops power noticeably when driving around town. I drive economically 99% of the time and do maybe one 2nd gear pull per drive which is short. My driving is primarily city driving but even without traffic in 80-90 degree heat im getting this issue almost immediately after driving for only like 10 minutes. Also my average gas mileage is 24mpg... this seems insanely low. whenever I drive at night in 60-70 degree temps as long as the car hasnt been driven constantly throughout the day the power seems totally normal. Anyone have this issue or know what I should check? I unfortunately dont have an ap yet.
