I don't know, maybe i'm trippin but, each time I leave a gas station with a full tank, my FD feels like it is more responsive as far as acceleration and pedal response seems better. I'm going crazy right?

Might just be that the extra weight aft of the rear axle is causing the car to squat more.



Might make you feel like you are making a little more power.

I must be crazy also, because i feel the same thing in the FD. Im pretty sure its all in our heads though

Are you sure its when you get a full tank, or do you have a power loss after you run down a full tank? I once had a car that every time i added fuel it felt faster. then i realized when i opened the gas cap air would rush in to the tank (like a gushing sound). My point is, the vacuum pressure in the tank makes it harder for the pump to do its job. Try leaving the cap a little loose.

I dont know but i feel the same way. Also i get a better hook up with a full tank i swear. But that has to be because of the weight. so maybe it does make you go a little faster on the low end.

Whew ok.. it's not just me then! Or maybe we're all going nuts! j/k. I think pressure in the tank has something to do with it and more gas in the tank makes more pressure in the tank making it easier to squirt the juice? I am just stabbing in the dark at this point. A weird phenomenon altogether.
