BTW, when my guage reads, it always hits from 17 to 14.5 and no graduals in between. Is my guage fcked up? or is it suppose to do that? I never had a car with a/f guage so i don't know haha.

For the thousandth time, a/f gauges that rely on the stock or other narrowband o2 sensor ARE USELESS UNDER WOT.
Unless your car is having severe issues, it is most certainly not running lean with a downpipe and catback. Not even close. All of those a/f gauges are pretty much a worthless light/needle show.

Yeah, if you want an accurate reading under WOT, a wideband 02 sensor is a must.
