    Well, my problem is stated above. I'm about to take a drive for a couple of hours and see if things get regulated by the PCM, but thought I would post and see if any of the experts out there had any input? Just to save time, I installed exactly per the instructions, everything is tight, etc. Any ideas?

    Possible you damaged the MAF during the exchange?

    2003 5.3L? You did not descreen the MAF, did you? Did you pull any wires loose in the MAF connector?

    No to both questions. It seems to be runnning better the more I drive it. Every once in a while, I'm still getting a little bit of a rough idle. Wondering if it just needs time to adjust?

    i had a true flow intake before i got the turbo, had no problems at all, it probably needs to learn

    Turns out when I reattached the neg. cable, I was supposed to start the truck with all accessories off and let the computer "figure out" the fuel requirements...Live and learn. Runs good now.

    Well I sold it when I went back to stock. I personally don't enjoy oiling the filter, so I wouldn't get it again. That aside, it served the purpose. I like my new route better - even if it is home made.

    i thought the true flow was a foam filter, so no oiling?

    Im looking at the different CAi's for these trucks, and cant make up my mind which one i want, im sure they all do the same thing, but there is a alot of differance in price among them. Im liking the volant the best
