For those of you who may have done shorty headers. I bought the bbk shorty headers. Installed them, a little tough to do i might add. ( in the backyard) BBk states they will go in with no mods required. Well when you go to put on your egr tube you find out another story, So i tried torching it and bending it to get it to work. But stainless steel is not easily maleable. So i got tired of trying. I fabbed up my own tube. Fired the truck up went for a drive. IT was missing and jerking under light throttle when you first let off of the gas. I discovered it was the tube itself. The factory tube has an orfice in it. So i put the same size office in my tube. Fixed the problem completely. Does anyone have any recommendations for a 2000 lightning as far as boost levels, Is a 6 lb pulley to much for a 2000 model (blow out plugs) or would you guys run 4 lbs to be safe
