Getting an 03 tahoe, opinions on mods and ?'s about tune up.

hitch is not mounted to the bumper like the s-10

fatnlow, I'm just wondering, but why would you do those two first? And it depends on what my parents will pay for.. Cause those first things will help with gas mileage. And I don't plan on raising it or lowering it but it will depend on what it looks like after the wheels get put on.
Timmy, yeah that's true. I'll just be happy if I get most of those mods done at all.

because you would have the wheels on which would be the main look on the truck and then get your rumble with the exhaust, and then u can add all the little other stuff to the engine after, but they are probably my 2 favorite adds on my truck

correct me if i'm wrong someone, but connecting the halos into your parking lights, they're gonna blink with your turn signals(same light as the parking light)...i hoooked mine into the drl's

 

[Gmoney_2010]

Do you think there is any way to connect them to the drls and parking lights? Or would that not work to well?

i'm sure you can, but don't know why you would. the halos suck for light output, btw.

 

[Gmoney_2010]

Do you mean the actual halo rings or the projectors?

on teh gas mileage/k&n

you can get your gas milage up considerably by simply replacing that ****** air filter with a high flow filter like a drop in K&N... under $80

Then add the Magnaflo muffler, its a straght through designe and sounds GREAT! should be able to get the part and have it welded up for around $150 if you do the leg work and shopping yourself. (got mine 100% done for $135)

i would also recomend getting the e-fan kit done, this dissconects the clutch driven fan and frees up some power.... I have seen this mod done for around $120 but thats you doing some serious deal hunting and labor yourself... otherwise you are looking at around $300

after all that is done GET A CUSTOM TUNE!!! this is the KEY element here... if you get those top three done up there and get a custom 91 octain tune, you can see a solid 3-4mpg increase.... when i bought my truck i was struggling to get over 14mpgs... i now stay stead around 17.5 and if i baby the shit out of it, i get between 19-20.... (i actually dont have the e-fans yet, but i want them and expect the gas milage to go up at least .5 to 1 mpg)

i also replaced my spark pluggs, fuel filter, plug wires and got a gold top battery... those things probably didnt hurt the truck either

I actually lost gas mileage with the k&n

yea thats my other favorite add on my truck, got my tint on prob 2 days after i got my truck lol

i have put a drop in K&N in every car/truck i have owned including a few girlfriends along the way, this has NEVER happened to me... my guess would be there was an issue with the MAF. Physics tells me that adding more air to your truck is going to give you better gas milage.... the MAF was most likely reading wrong at some point and not creating a stable mixture.
