so i was noticing that my fuel gauge has been moving faster tward the left side than it used to, only going about 200 miles on a tank (i used to get 300ish). and my car feels like its lost power. i just put in a new racetronix pump and hot wire kit. the plugs are a little old, about 8000 miles and 10 lbs of nitrous, but they looked ok, just a few specks from detonation. what do yall fellas think could be the problem? i went lean a few months ago on a 150 shot with the stock pump, but it seemed to run fine after that. new plugs, maybe some MSD wires goin in this weekend.

 

anyone?

 

I assume you changed the fuel filter as well? Check out your tune and see how everything is running. Look at your 02's and see if they are also getting dirty, etc. Quite a few things can result in power loss/increased fuel consumption. Fuel Trims getting out of whack, hurting a cylinder (Piston Ring, etc.)

Let us know.

 

i forgot about the o2's. ill check those tomorrow.

 

Usually if the 02's get really clogged, it will toss a code, but pull them and take a look. That and the fuel filter/plugs are the first things to check.

Good luck with it man!
