Just wondering since there are some people running 4lb pulleys without chips. I know chips are used to retard timing but less than the stock computer or just less than the street program. NX even state on the kit that no chip is needed or timing be reduced.

SVT_FL, You need a chip to run nitrous. I don't think that it would be a good idea to leave the factory 1-2 shift like it is where it drops 4 cylinders right before the shift and you are spraying. I would just get a good nitrous chip and pick up the extra 3-5 tenths from the chip plus whatever size hp shot of nitrous you're running!
