First question is.... why are you against getting the car tuned properly if you intend to mod it?
For the cost of a chip and a base tune these days to get you started, there is no excuse.
If you use a C&L with a sample tube for your stock injectors, and leave the injectors alone then you will not need a chip, but neither will you be in the range of air flow to max out the stock MAF so why bother with the upgrade.
If you decide to move up to say 42# injectors with a larger C&L with the proper sample tube, then you are leaving alot of power on the table AND more than likely damaging the motor in the process... such as too much fuel at startup since the MAF isn't used at startup, too much fuel or not enough etc while the car is in OL due to nothing correcting the fuel delivered and the scewed load numbers, and because of values being altered from true state, spark timing is thrown out of wack so you would be getting too much timing at the wrong rpm/load etc.
In other words, if you are modding, get the darn thing tuned for the mods to get the most out of the mods, AND save your motor.
