possible loss of hp on 2009 Mustang GT500

i feel like my 09 gt500 has lost hp over the past 2 months. has anyone noticed a hp loss in their gt500? the only mods i've made are put eibach springs on front and rear and put AR shelby razor wheels on it. the wheels are heavier than stock but not that much. anyone have a similar issue?

It sounds like you've been parking it near some Kryptonite.

The Adaptive Learning in the computer could be adjusting to you.

Do you typically drive it like a grandma? If so, go beat on it a little more frequently.

I am not sure my response is even worthy...

but....I have a 2008 gt500...and it feels soooooooo good every time I drive it.....with that said.....I only have 900 or so miles on it. It still feels as assured as the day I learned to drive it.

Be passionate about your car...it IS a good thing.

+1

At first, a car like that'll feel like a demon everytime you drive it. After a while though, normal driving tendencies are figured into the programming, making it a little tamer. If you beat on it for a bit, it'll jump back up. Doesn't take long.
