so it bogs when you get up on it?might be leaning out? do you have a wide band?check your air/fuel ratio or your spark plugs for detanation(white marks on the top of the spark plug)

what is this "wideband" people talk about, what does it do and how much do they cost? and where can i get one?

aem makes one instead of the light show that u get when u buy one of those autometer air/fuel gauges that really arent accurate(like 10% accurate actually) the aem wide band comes witha o2 sensor plug.. plugs up to your downpipe and acctually reads the a/f accuratly ..much..much more percise cost like 280-320 new comes in a black 52mm or a white 52mm gauge feally nice you can get one on ebaymotors or at INTERCREW in garland tx going over there this afternoon ill see how much exaclly it costs when i get there
