Do I need to change my chip, computer?

did you get a matched mass air meter to go with the 24# injectors. thats your first step. as far as a chip, i doubt its needed for this small amount of mods. tweecer is a laptop based tuning program.

Well, without a matching MAF cal'ed for the injectors your gonna run rich, a chip will fix that as will a tweecer.

A tweecer piggy backs onto your comp to allow you to self tune your computer, in order to self tune you really need a wideband plus the r/t version (around $1000)

Then you gotta learn how to use the tweecer and how to tune, and with those little mods tuning really isnt needed and would ALMOST be sort of a waste. Granted your car will run smoother and you get a few hp, but it isnt really needed.

As for a chip, that would be a waste, paying $300+ for something that isnt gonna do much and isnt needed would just be dumb.

You can grow into the tweecer and tune for every mod you get, the tweecer will pay for itself int he effect if you were to get a dyno tune and a chip burnt for every change in your combo once you start makin some numbers. plus its alot of fun to learn your comp and tune it your self, I think at least.

All that being said you really need to consider what you want to do, how much you wanna spend now, how much research you wanna do, ect.

Easiest route: get a cal'ed MAF for the 24# injectors and be set for awhile, you'll be good until you start doing some major mods.

Most expensive/harder route (but worth it imo): The tweecer or other self tuning device such as the PMS. But agian you have to learn the programs and shell out a pretty penny to get started with those.
