I think I'm around 8-10 mpg at the moment - mods in sig.
Just curious if I could do some swapping out of parts, maintain performance, but improve mileage?
STS systems are so cheap now (used), would it be worth selling my headers and roller rockers for example and putting the proceeds toward a used STS kit? I know I would still have to throw some additional cash at it, but would that improve mileage?
Any other suggestions? Procharger?
Turbo turbo turbo. I remember when gran nationals were runnin 11's and getting 30mpg.
Any idea how/if a Procharger would improve mileage?
why wouldnt you just keep the headers for the swap to an STS kit...prob wouldnt be a bad idea
Thought you used stock manifolds with STS.
I dont think it matters...turbo is no where near the manifolds or headers...it goes back where the muffler isQuote:

Ducky went from tubes to manifolds after he STSed. Come on duck man pipe up. and tell how it worked.
Some people say that it is better to run stock manifolds with a turbo because you retain more heat within the exhaust system... I would think that wrapped LTs and a free flowing exhaust (not too big of dia.) would be better for an STS setup.
hey are we suppose too answer this so youre wife will let you get an sts.?if so yes youlle get waaay better gas mileage.lol,j/k
Been there done that, the stock manifolds work much better than LT headers. I got 18 mpg in the city and 22 mpg on the highway with the STS kit. The 22 on the highway was running between 75-85 mph. Once you are up to speed it never shifts down no matter how steep the grade. Stock 5.3 with 918 springs and a 2600 stall.
Pretty much...lol...Quote:

z2.. Sound quality is a little less with my setup now, but the spool time is alot fasterQuote:

Could the odometer/speedometer be off some, too? It all adds up. Get a GPS and go out and measure your speed.
Mozes tune is fine...it has been looked at by a couple of the best tuners in the area...
Dustin did the tune, Sean at LG looked at it, then Sam looked at it and it's all good.
LOL...Virgil, funny enough--I suggested the same people who have looked at it...
Those guys were probably looking at only the performance end of the tune. The economy that you're looking for is totally seperate and takes a lot of tuning to fine tune to work through all the cells.
no Greg, Sam and Sean both went for rides...Sam is the one who always helps me when i have problems..he made a couple of changes a week or 2 ago and got me a lil over 1mpg better
What mpgs are you getting V? I logged mine this week and it showed 17.8 mpg city/hwy mixed...
Moze, if I am getting damn near 18 mpgs in an ECSB with a 5.3L with a decent amount of mods and a tune that is out of whack, you should be getting close to 15 in a LQ9 RCSB...
well if i cruise 70-75 i get 16-16.5 anything above 80 and i get like 14-14.5
ok so any ideas as to why moze is getting such crappy gas milage? is it just the fuel eating 6.0 or what?
he dont know how to add???
I'm doing very basic math...maybe I'm off (boy wouldn't I feel like a tool)...
I believe it's a 20 gallon tank, and I get around 200 miles per tank.
you cant do it like that...fill up reset the trip drive it around then fill it back up...then you take whats on the trip...say 232 and it took 18 gallons to fill it then your gas mileage would be 12.88mpg...the only way you can do this is start with a full tank and end with a full tankQuote:

man that thing is a gas hog... a lot has to do with how you drive it as well... but still i would think that you can get more than 200 miles to a tank...
I wonder if the tune goes into power enrichment mode too early. Now is that city driving or mixed city/highway or straight hwy?
Mixed...just my normal weekly useage...HOV lane to work, around town to get to the HOV...a few WOT runs here and there.
Are mufflers need/typically used with turbo?
I have stock manifolds/stock y pipe just mated to the turbo. Getting into the throttle it doesnt sound deep or throaty, has a slight tune to a glass pack, but its not that bad. At cruising my truck is reallly quiet with just the sound of the whistle, full throttle, its loud. The turbo is soooo loudQuote:
