I have not done any performance related mods to my Tahoe yet but I have a few planned. I wanted to get some guidance on which order I should do them in, maybe some brand/product suggestions, or anything else to add to the list.
Vehicle: 04 Tahoe LS w/ 4.8, 93k miles
My goal is to get a little more power without sacrificing MPG, maybe even gain some MPG. Most of my driving is on the interstate with lots of hills and it likes to downshift for long periods of time. I've also got a lot of weight in the back due to my sound system (400 pounds or so, will be closer to 700-900 soon) and a dual alternator setup (stock 130a + 370a hairpin from Mechman).
So far, I've planned out these upgrades:
Tune: I've heard good things about the BBP tunes. HP seemed to be decent as well.
Intake: After doing a price and performance comparison, a volant intake with a dry filter is most likely what I'll use
Electric Water pump: Haven't looked into this yet but I've seen it referenced quite a bit.
Electric AC: Didn't find much about this yet but saw it referenced once or twice. Same as above
Exhaust: Another I haven't really looked at. Not really looking for loud, just something with a nice sounding deep tone and/or performance gains without breaking the bank. I do have to go through emissions though.
Cam: I'm not sure if I'm comfortable messing with the internals of the engine myself so I'd most likely have a pro do this part. As such it would probably be the last and most expensive part.
Another not so performance related mod is that I'd like to add some sort of switch to up my idle if possible so that I can rev up the engine to get the alternator output to its maximum level without manually pushing the pedal. I wouldn't want it revved up all the time at idle, just at audio shows/competitions.
