Wow thanks for all the input. Here are my answers to all your questions.
My elevation is 6800FT, Colorado FTL
I got a new exhaust since the 0-60 timing i did(got 7.82-8.13)
My Plugs are new, no oil consumption replaced at 75xxx now 84xxx
Tires are new summer tires
Weather is 70 degrees +/-
When i launched it was just from a dead stop, no power braking
My MPG is decent, i get about 18.5-19.3 MPG running 91oct
I drive my car fairly hard, so i feel the ECU knows me haha.
Ive done the ECU reset maybe once every 3 months or so.
My AFR and compression is a mystery, I did throw 1 code since ive owned her and it was for the throttle body. Cleared it and never happened again.
Im going to pull the plugs soon to see if OC is going on. I just bought new Berk Cats, Motordyne plenum spacer, apexi filter for stock box, and grounding kit. Im hoping these will help me eliminate heat soak, possible clogged cat, and bad electrical current. Then after all that DYNO tune to see what my AFR's are cuz i feel like they must be wack.

before you do anything crazy like tear down your engine i think the best move you can make is to have the car dyno'd and when they do it make sure that your air fuel ratio is recorded. also you should keep in mind that a 6mt is listed as doing 0-60 at 5.4 with a pro driver, with a normal person probably closer to 6 and as much as u probably dont want to hear it a 5AT will be probably 7 this car is alot heavier than it should be and AT's dont do as good with weight. if the dyno numbers are alright then it may just be time to put in for some more mods. also a base model G6 is listed as 0.3 faster than a 6MT in a quarter mile so even though its a ****box it probably weighs 800 pounds less

Your 8-second 0-60 time I explained in another thread you started here.
Comparing a 280 or 300 horsepower G35, with 260 or so ft./lbs. torque to a 300 horsepower GXP with 320 ft./lbs. of torque is not going to result in a favorable outcome for a stock G racing in a straight line. There's more to performance than just horsepower, and the V-8 powered GXP simply has more muscle.

Okay, so ive been killing myself trying to find out why my car is so slow. I have a 2005 G35 Coupe 5at with exhaust and Z-Tube.
Basically, im one of those guys who posts 8 Second 0-60 Sprints. TOTALLY SUCKS! Do you know what its like lining up to a Pontiac G6 GXP and watching him walk away?? Its worse then being stabbed repeatedly by a short knife. At least being stabbed would kill you rather then catching a G6 at the next light and he just points and laughes...
So im asking, all of you, what would you suspect as the reason my G is so slow? Pretend this was your G and please provide input..
Dont gimme the "its an auto" crap, thats just not helpful or funny. Ive changed the spark plugs, installed a new PCV valve, new exhaust(thinking it was kinked or something), cleaned the MAF, did ECU rest, ran her cold and warm with no real difference, no oil consumption, running full synthetic front to back, cleaned the throttle body, and basically prayed to multiple gods hoping for divine intervention... (no fix still hahaha)
2005 G35 Coupe, 18" wheels, 91oct, 5AT, VLSD
Heres what my car does:
-Idle drops to 600RPM-ish, sometimes the bottom part of the needle drops below the 3rd tick on the RPM gauge from 0
-Strong smell of gasoline when i start her from overnight sitting.
-SMALL amount of oil leaks from the bottom(size of a .50 cent coin), looks like its coming from the oil filter. Had it checked by 3 shops and none of them could tell.
One time my car fell flat on its face from a stop light and my throttle body failed. Turned off the car and it went away. Shop cleared the code saying it was throttle body failure but it hasnt happened again, ever.
Thanks for reading all of this, im just really at my whits end with this. I know 0-60 dont mean crap and street racing is stupid. I dont street race ever, sometimes i need to change lanes and Dbags wont let me. Its nice knowing i can pass them but sh!tty knowing i cant.

I ranged between 5.8 and 6.2 sec 0-60 at 34 feet altitude

well maybe 7 seconds was a bit much but i know that it isn't going to be as good as a 6mt and i know that the 5at cars i have watched dyno'd at the shop i do mine at usually pull 35 to 40 less horsepower but it is a mustang brand dyno they arent that friendly. also 6.2 at 34 feet? what do you think the difference will be at 6800 feet? i guess everyone doesn't get the pleasure of being at sea level.
