Hi I'm new to this forum and hope to get some good info on what I will do with my 2002 Tahoe. I already put in ac delco iridium spark plugs, im working on a diablo trinity system, and trying to find a good CAI and whether or not it will work for better fuel mileage. I use my tahoe for my business for Pilot/Escort and I put a lot of miles on it, so I'm looking at all the ways to increase my MPG. I also use RP oil and am loving it.

Welcome to the neighborhood!

A CAI would help in the grand scheme for overall efficiency. Making sure ALL your fluids are synthetic would help to improve things a bit too. Overall I would make sure that everything is in good running order, make sure the MAF and throttle body, depending on mileage you may want to go ahead and replace the O2 sensors even if you don't see any apparent issues. Make sure that the suspension is all good as well, especially in the front IFS and steering linkages to ensure everything is tight and operating properly.

Thank you im working on the cold air intake atm but it seems CAI doesnt have one for my vehicle and i want to try theirs out since i've been hearing good things thus far for them. I have inquired if they will be going into the older years so im waiting to hear on that before i make a decision on what different to use.
