fuel injector questions

[faddis]

ive done some mods to my car...now i keep getting a check engine light...its the p0171 code...im running too lean so i bought new injectors. I bought 26 lb injectors. I was wondering if i will need a new fuel pump or if our pump will push another 4 lbs. need replys fast...im heading to the track this weekend.

ohhh yeah is our fuel pump the same as the z28 fuel pump???

Check your O2 sensors near the converter, or try an O2 sim.

Dunno, never ran N20 in any of my cars. I would guess that the O2 sensors are reading the lean condition, and throwing the code though. As for the lean fuel, I'd definately fix that ASAP!
Go to the "Nitrous" section here, and ask. They would be able to fill you in better.
