My 94 mustang gt is starting to get a little weaker since i have been driving it hard for the past couple of months. I am getting used to the power and need a little more hp to suit my needs. I dont want to put gears in right now because i do alot of highway driving and i drive 80 all the time and i dont want my gas mileage to drop. I was wondering if my car would hold up to a small shot of nos, maybe 50 or 75. Or i was wondering how much a good chip would be, how much hp and torque it would add, and is there a way to like a tuner with presets so i can go with like a stock tune one minute, then when i line up to race the locals, push a button and have more power. I like the idea of more power at the push of the button.
