egr delete after thought question
Ok so a few weeks ago i did the delete and studs.... took a little while for the truck to run like it used to as far as power. I am sure thats pretty much just the pcm re-learn so that is of no concern. I have had something cross my mind however. I have an 04 so that means i have that throttle butterfly deal right under the intake elbow, i have read that it is there to force the engine into drawing in more exhaust gas by closing up a little bit. Now that i have the delete should i also pull out that butterfly? I can only assume that it still acts as it did while i had the egr cooler installed.
