Said GTP might have been knocking? Tired transmission? Crappy long gears...driver mod, etc.
P0171 is a vacuum leak, my piont somewhat proven. Enjoying the crappy MPG's? I know I was with a P0171.
How do you not know if you have any codes?

My check engine light is dead, i know that for sure.I got scanned for codes a few months ago it was just 2 that i already knew of.But i gotta check again asap wanna know if anything is wrong.
Put a new bulb in it?
Yeah, but its just 4 bolts after you pop the plastic crap off.
Like other people have said a ported throttle body would be a good option. You could also get a ported rear manifold from ZZP and a ceramic coated crossover. You may want to get a larger exhaust although the stock exhaust should be fine for the current mods. You could always get a GT2 cam rather than a GT1 unless you dont have money to get a tune. I believe a dyno tune from ZZP is only about $150
Why is a ported TB a good option?
It does nothing for gains really.
Ceramic coated crossover is a waste of money, its a 3800...the motor is going to get stupid hot regardless, and the rear manifold is the LEAST of the 3800's bad exhaust issues...see U-BEND, FRONT MANIFOLD CASTING, DOWNPIPE.
Larger exhaust piping is also a waste because the factory catback is good for 300+ FWHP before it becomes a flow restriction. If you want a different noise, change the mufflers and tips. Like I stated before, the GT1 and GT2 are nearly identical...also, get a custom in car tune...they are better than ANY canned tune.
No, system one bank lean means a vacuum leak.
Find it and fix it.
