i wish they made one for the denali.... i guess im just going to have to paint the stocker

no answers? damn where u guys at? i ended up just replacing that o2 sensor and it seems to be ok... 2 days no new codes... so i guess that was it

so im driving to work last night and my check engine light comes on. it seems to be running fine... i get out of work today and its idling rough at stops. so i stop and read the code at my old work, and its comes up i beleave p0154 bank 2 sensor 1 (upstream) no activity... so what do u guys...

im not gonna lie man usually i like 20's or 22's but those dont look bad at all... i might think about going smaller with my nali... they look real good man..

yea the denalis are all time awd and i guess it does make a difference... it doesnt seem like boost gets as bad milage as i do, but he does have more work done to his nali then i do....

hey would u mind running one for me?

damn fellas you seem to be getting much better milage them me. the best ive gotten with my 03 nali with the 6.0 is about 270 to the tank (filled about 22.1gal). bone stock except for a K&N drop in. wonder why mine is so much lower? i dont drive to crazy and its a good mix of highway and stop and go

yea mine has 90k and ive done all the filters just havent gotten to the plugs and wires yet... however i did check my tire pressure today, because when i first got the truck i had much better mileage then i do now... i made sure all the tires had 35psi when i got it.. just checked them all and...

damn jsho what am i doing wrong? i average 11-13 in my 03 denali and thats being nice... if i romp it, i can literally watch my gas gauge drop... getting about 230mi. to a tank... thats with a mix of city and highway... and i have a k&n drop in.... made no visable difference

just did this mod to the denali and its pretty sweet... of course i did the 6 high mod haha... great write up rt... are there any harmful effects of this? strain on the electrical system? the be honest i dont know to much about diodes and jumping relays, so i just did it because it worked haha...

ive been told that the motor and tranny are bullet proof in these awd systems... and with a mix of city and highway driving im getting about 13mpg... i have no clue how blizzard gets that good of mileage but i want to know his secret

i would have to agree with blizzard, my 03 nali hauls ass and you can watch that gas guage just drop down. ive had it for a few months now and the only issue is the rear heat wont blow anything but ice cold air... that is what the waranty is for i guess... but i love the truck cept the gas...

where do i find the diodes? and what exactly am i looking for, i would like to try this on my 03 denali

from what i understand the auto leveling air ride "deflates" after the truck is turned off... everytime you start the vehicle it refills and adusts for the load. someone elese with more knowledge might know more but that seems to be what ive come to find out. i have the same system on my 03...

anyone with ideas?

from what ive been told that grille bolts right up to the yukons and tahoes... you just need to replace the parking lights assembly... i dont think there is an issue with having the non denali front bumper

hey guys i just picked up another stock grille for my 03 denali and i thought it was complete, however it did not come with the bezels for around the parking lights... its the whole assembly and has the mounts for the bezels but they are not there... anyone know where i could find them? or does...

funny this thread is right on top because up here in pa the temp has been dropping down to the low 30's the past few days... so i turned my rear heat on when i had a few friends back there and it blew nothing but cold air... gave them an icy surprise haha

yea its definatly a camber issue. i have a honda track car and its lowered and you can visibly see the negitive camber (top of wheel leaning in). so my tires wear horribly... however a slight camber problem would be hard to spot especially with stock wheels and tires... so a good alignment would...

i had 35% all around on my last truck and got hassled by police here in PA... they have tint meters and all. it really depends on ur locality. in PA the law states that any aftermarket tint is illegal. the only legal tint is what is from the factory (like the privacy glass on our trucks) but...
