Maybe they should re-name the company to Adapt-abrock!. I know how you feel--the EGR valves on my two vehicles that came with one required their removal,I made a block off plate.Some vehicles will ping bad enough to hurt things without them though,then you have to retard the timing and suffer some power loss--mine doesnt ping,guess I got lucky.
Its a pain when nothing just bolts on,and you need all those special dewhickies they only sell at speedshops open only when you work--and when you sneak there at lunch hour,of course they dont have it,gotta order it and wait,make two trips--isnt this fun! This is why as I get older--factory parts look better all the time.Sometimes I wonder if all this "high performance" stuff is any "higher" than chevy made it themselves!. /forums/images/graemlins/confused.gif /forums/images/graemlins/dunno.gif /forums/images/graemlins/thinking.gif
