Awesome. I appreciate all the replies. I would agree that they are very safe. When my wife is driving our daughter around I always feel confident that they will be ok.
Did the chip mod actually make a difference?
What does that up/down switch next to the shifter do?
Does it just change the shift points?
I spoke with a mechanic who stated that I needed to have my car's computer modified after the oxygen sensor was changed so that I would get my fuel economy and performance back. I am guessing that is a bunch of crap. I just removed the negative battery cable after replacing the oxygen sensor.
Reprogram after o2 sensor sounds wierd, never heard of it.
THe chip does make a pretty big difference, but mostly in your flat spots, idle and upper RPM.
initial accel. is improved, but not HUGELY.
one thing i dont like about my chip however is that it gave my car an increased idle speed and the car doesnt adjust to going from no load to full load as well as before and the brakes were also a bit weaker
