hey guys, i know theres probably a metric ****e tonne of posts about this, but lets see what info i can drum up...lol im looking to get rid of the lag my truck has seemed to develop after i installed my CAI and cat back exhaust.. (i would equate it to turbo lag, lots of noise, not much get up until about 2500-3000 rpm then the power kicks in) i also have black exhaust tips (and i run gas lol). After doing a little research, i believe im running rich, does this sound right?? if so what tuners have you guys used that you would reccomend?? thanks in advance! ps. i also need to calibrate for the bigger tires i recently intalled..
