Just trying to stick to the facts, running a CAI in conjunction with a programmer with canned tuning can often result in a lack of performance due to an excessively lean condition that is frequently observed with that combination. We have personally dynoed trucks that made good power gains and then lost power simply by bolting on a CAI. After tuning to correct the lean conditions, everything was back to normal.
Now, is this what's happening with you truck? It's hard to say. Every vehicle is different, every CAI model responds differently, and there are hundreds of calibrations that each have minor tuning changes that affect overall performance. In general, I'd say that going with some custom tunes would be helpful in providing that "wow" feeling.
I hope this is helpful.
On edit -
Somehow missed that it was on '01.
CAI kits on those don't suffer the overly lean conditions that late models do... at least not to the same degree.
