My LTFTs are at 25 on both banks on my car, but my wideband reads 10.1 afr, whats going on and could that be a reason my car runs like s***.

When does your wideband read 10.1 and your trims show 25, during idle, cruise or wide open throttle? Example, if it is during WOT only, this means that your fuel map is way to lean during cruise setting the trims high and applying extra fuel at WOT where it doesn't need it. You may need some custom fuel tuning, especially in your cruise area.

No its like that all the time idle, cruise, and WOT.

My first guess is that your two upstream O2s are not functioning either because they are not getting warm enough do to your LTs or they got contaminated do to a previously over rich condition. With your HPT I would force open loop and program a lean idle and see if those O2s respond to that. If not, try new O2s first.

I say replace the motor, rear end & seats honestly get to the bottom of the problem before you just start replacing part after part, are there any codes showing up that might point you in the right direction?

No, no codes at all, and I have my wideband functioning as the narrowband also on bank 1, but I have no idea.
