Questions on my 99 gt

[ninjastang125]

for 1 I have a steeda timing adjuster on my car and currently the timing is set at 12*. I was if bumping the timing up a degree or two would cut any time off of my 1/4. if i were to bump it up would i have to run better fuel? also i was looking at the sct 4 bank chip. has anyone on here used it and would it be better to get the flash tuner or the chip. which one will provide me with more gains? thanks in advance.

i actually think your running too much advanced timing.

usually with a reflash tuner(example: Xcal 3) you can adjust the timing anywhere from 2-4 degrees advanced. i doubt you will see any faster quarter mile times. just better throttle response. I ALWAYS suggest getting a dyno tune by a reputable shop. a 91 octane tune might yield you a few horsepower. but nothing crazy.
