Alright guys i just got a 2007 tahoe 5.3 flex fuel fully loaded with 4wd all black.

I would like to add some upgrades on to it hopefully to improve the gas millage. Here is some add ons im thinking of doing please let me know if you have any ideas or more i should do. Thanks

Chip programmer:
What one should i get because i have the 5.3 flex fuel and it has that stupid mode where it turns into a v-4 i want more power on blast off but then i would like to have a option to save gas. LOL Will it mess up the truck v-4 mode?

Head unit:
Also if i put in a pioneer touch screen in the tahoe well all the remotes work like on the wheel and the back seat.?

HIDS:
What kind of hids can i install? also is there a way to make the running lights, low beams, and fog lights all stay on at the same time?

 

filter - wont really do anything for your mileage unfortunately other than let you go longer before you have to replace/clean the filter
TB spacer - wont do anything at all
Chip - search blackbear tune, best I have seen. lots of info on this site
head unit - there are additional parts you can add to keep the factory interface. just talk to your local installer.
HIDS - do a search on this site. Why would you want to make all the lights do that? You are not an 18 wheeler. right now your low beams and fog lights on at the same time is more than enough.

best thing you can do for mileage is drive very lightly - even still don't expect more than 15 mpg in the city with a 4x4
these things are big and heavy, learn to love it!

 

Save your money and look into the Blackbear tune. It's cheaper and it works. You just tell Justen what you want like better mpg or more hp.

ousig2408: During my tenure in the Tahoe forums the past few years and observing local drivers, I've discovered that there is a group of really cool folks who drive w/ their fog lites on, some even do it in the daytime.

 

If ya gott'em light um up I say

 

Alright so where do i get the stuff to do it lmao.
Does anyone up grade the fog lights or keep them stock?

 

i got K&N cold air intake - can find on eBay 250 shipped. Engine is little bit louder and K&N claiming 1,5 MPG better gas millage.

I think, the best way is black bear. I was looking for supercharger but still too expensive. U can get cheaper "wet shot" but i hate to do it on plastic manifold.

HIDs yeah, u gonna need projector lights.

 

Google is ur friend.
