i was saying run the dyno before and after the k&n install just because your numbers with the borla seem a little bit low... if you compare to those numbers, it might inflate the true gains with the k&n. would be nice to get a new "base" before the install.well i will run the dyno again after i install the k&n since we already know what it runs after the Borla it won't be hard to figure out. I am not sure however what Borla was claiming. I was showing a very low air-fuel ratio, anyone else had problems with this? Not usre on the numbers exactly, will get them when i go back Monday.
