A chip can increase your performance... but not very drastically. If you are looking for a drastic change I would go with a Supercharger or NOS, but that can mess up your engine. If you have your mind set on a Chip, I would check out Saleen's POWERFLASH Automotive Performance Computer. It isn't exactely a chip, but its better. I don't know if the POWERFLASH works for the '98 GTs but if it does it should increase your HP by 20 and also increase the driveability. You should be able to find some info on the POWERFLASH at www.saleen.com. If you want a chip I recommend getting on yahoo and doing a search for something like Mustang chips.
If you don't know anything about chips, basically they are small computer chips under the dashboard that control the cars performance. As you can prolly guess, a better or more expensive chip increase the performance of you vehicle the most.
sorry i think you guys mis-understood me...i relize that the car has a computer and i know where the chips are, i ment to say does any one know what chip i should use for high performence for a street aplication...thanks migraine
