Just wondering what kind of things could go out of wack after car was running with NOS. Seller deceived me and didn't inform me of the NOS and insisted that the car was never tracked, etc... The trunk was filled with a tonneau cover and two car covers so I didn't see the holes drilled when the tank was installed.

All in all, the car runs great, can't complain, although this shitty mpg is getting on my nerves (230miles/tank).

The car has a Injen CAI as well... Lowered with KG/MM springs and sitting on 18" wheels.

Common 18" wheels with NOS? Why?!

Are there adjustments i can do or things I can inspect further?

 

You sure it was nos and not an amp that was removed? I think an amp is more likely...

 

100% not an amp considering there are 4 holes on the driver side of the trunk, then a bigger hole for the line in the recessed part of the trunk...

 

The 18's are playing a role on the gas mileage, but your not off by much. I get around 250 miles on a take of gas on OEM Wheels

 

I have an '02 and only get about 220 miles/tank. I don't think your car is abnormal in that respect. If you want to spend money for piece of mind, you can always do a compression test.

 

no, increase weight will decrease gas mileage, the wheel being bigger doesn't always means it's heavier, my 17x9 was lighter than my oem 16 for example.

check the compression for the starter.

is there anyhole in the intake?(dry kit?)

 

WTF?

 

Compression and leakdown tests should give you a pretty good idea of the general health of the engine internals. Both are pretty simple DIYs or inexpensive at a mechanic.

 

For his sake I would think he meant to say "as a start" or something like that... not "the starter".
