looks good bro... hey hows your MPG? I havent driven much on the highway since my lift but my City MPG sucks! lol

Prob my heavy ass Toyo M/T's... but they look kick ass! haha

my highway is in the 20s all depends on the day but i got 21 the other day pulling my 1,100 lb pop up camper at 70 for a 20 mile stretch on smooth black asphalt.. never broke 2,200 rpm..

and my city is averaging around 15.5-17 with ecu remapping.. and i never go above 2,000 rpm. and have no problem keeping up with traffic.. i drive in a manner for max mpg.. and if i put my foot into it fuel economy is non existent.

Everyone gets different mpg.. lots of factors go into this.. the grade of fuel. how clean the fuel system is. road surface. tire balance and resistance. throttle pressure. air temp. and how well the engine has been maintained over the life. Mine has improved based on how i drive,, and the work that i have done to the truck.. also i dont pay for gas so not a huge deal i mainly want overall distance per tank.. my new full length headers and no cats and O2 turned off should yield another couple MPGs.. im shooting for 18 city and 23 highway averages. but those are numbers but i doubt i will get them...


also i have horrid gas milage in the mountains.

my averages are with high test No ethanol on flat smooth black asphalt in charleston, sc at 0' sea level when it was 79* a week ago..

Edit: also my city driving is well... i drive 3 miles @ 45 mph and hit one stop light. so it is not rush hour traffic fuel economy.. i can do a calculation on the next tank i am in heavy traffic and average the 2.. but i only drive 12 miles a day in these conditions to and from work and home for lunch.. so they are probably better numbers than say someone sitting in Atlanta GA traffic or big city traffic..

I about fell in the floor when u said u are shooting for 23mpgs hahahaha gl with that. I don't care what u say no way u got 21mpgs pulling something

 

[jdpber]

if you read i said my self i dont see 23 happening but would love it to be there..

and i had a tech ride in the truck for 2 hours building custom mapping.. custom intake. custom exhaust mapping and air fuel.. this is a step above the BB tune because it is specific to my vehicle.. and i am going by the dash fuel gauge estimator.. so unless my truck computer geometry is off then my mpgs are correct.. i just filled up on way home and i went 342 miles and put 20.6 gallons.. and i divided it out and that is 16.6 mpg. 90% city... so that is what i am going off of....


and read i said ""im shooting for 18 city and 23 highway averages. but those are numbers but i doubt i will get them...""

these are what i would be loving... that is all.. never said i expect to get there.

There's nothing "custom" about a cai they are all the same whether u bought it or somebody "custom" made it for you. If you paid for a "custom" exhaust it was a waste Bc the stock piping is more than adequate for the hp you are making. I see you have a blow master which is one of the worst flowing mufflers in the market. A simple straight thru muffler is sufficient. Now the only thing "custom" is the tune. You will be lucky to get 18 mpg on the hwy due to so much wind resistance u have. Not trying to be a downer and all just being realistic.

if you have a lot of straights @ 45MPH i see you getting 15MPG...
I think mines at about 12-13MPG in the city. I see more stop and go. On the highway mine is nowhere near 20! im more like 17MPG tops! at 70MPH there are some ups and downs on the highway though. But 21 and pulling something, I do find hard to believe.

My truck is HP tuned w/ a K&N CAI and Borla Exhaust.

Bruce - to clarify what was stated.. "custom mapping.. custom intake. custom exhaust mapping and air fuel.." MAPPING in the ECU.. the ecu was re MAPPED CUSTOM for my exhaust flow rate with the other combinations.. I never once said word one about exhaust pipe, or muffler.. only stated in getting headers and no cats with O2 turned off.. never did i say anything about the exhaust piping.. and yes i do know that the factory pipe is adequate to flow..

Arctic.. i pull ot the drive go strait and a slight bend. stop right turn strait for mile and half and a left into the shop parking lot... 45 the hole way for about 2-3 min..

If yall feel that my numbers are off then i will look into it.. but i am going off the dash computer.. and it could be off if i am 3-5 mpg higher than yalls.. i can only go off of the dash and the fuel pump at gas station. and i still need to have the speedo re-calibrated bc it is off a little from my gps.. 2-4mph varying some days it is spot on and others it is off.. now that yall stat yalls numbers and i think about it there may be a connection.. this will need investigation..

Im not jumping just thought i was doing good.. and now yall make me doubt my actual economy that is reading on the dash.. I am going to get paul to scan the ecu and recalibrate the speed sensor this weekend and burn a tank and see if i get different results.. i simply was very happy past 4 weeks seeing high teens and hitting 21 on highway ACCORDING TO the Dash...

thanks for yalls numbers for comparison guys..

I'm new on here but I have a question for you I have an 04 tahoe six inch lift with 35's cai tb spacer with tru duel exhaust and 456 gears and I get 12-13 in town and 15-17 hwy. Did you change your gear ratio or you running stock?

Sooo in other words there's nothing really custom. A guy tuned ur truck with hptuners on a lap top. FYI a knowledgeable tuner should take no where near 2 hrs on a tune

 

[jdpber]

Im not going to argue.. bc i never said anything about the exhaust.. and the tune is the custom part.. and it felt like 2 hours not 100% that it took 2 actuall hours.. no one asked you to be an ass.. and i never did anything negative to you.. so please chill.. it is custom to my application..

All that truly matters is i an happy with the car and i get the miles per tank that i am happy with.. so discussion closed..
