auto tune 02 sensor

[outback_imp]

If you are doing a full exhaust- you should definitely add fuel or you will be running lean.

You don't 'need' the autotune- a power commander by itself will allow you to add fuel...the autotune just does all the adjustment work for you and makes it the best it can be.

Thanks PD, Thats what i thought too after hours of reading about it on this forum.
So now im not really shore what i should do? Keep in mind im not looking for a bunch more hp , just a louder sound more like my old bikes sounded. one tells me with a full exhaust being the "only modification" , all stock on the intake side. im better off just plugging the stock 02 sensor back into the new header?
And you say it will definetly run too lean.
Too lean to where it will cause damage to the engine??
anybody else want to chime in and give me their opinion?
I already have the pcv and auto tune box, And if that is going to make it run better ,maybe a little "cooler", and not give me horrible gas milage, id be all for it.
