Lifts don't cause a decrease in mpg...

 

they mess with the aerodynamics, and driveline angles(and sometimes weight depending on size and brand) which can mess with fuel mileage.

 

I prob need a tune up.. what do you think about a K&N AIR FILTER

 

IMO the K&N drop in filters are more trouble than they are worth. if you want a cleanable filter then get a amsoil replacement filter. if you want more power and a cleanable filter then get a cai and you'll need a custom tune to go with it or it'll run lean. whats the mileage of the truck? if you already have a K&N filter then clean the maf.

 

i thought i got about 18 mpg but im not sure. So getting a K&N AIR FILTER isnt worth it?

 

to some people it is, to me its not. it will give you slightly better gas mileage and i think more towing power but thats the only time you'll notice anything at all as far as performance and mpg. otherwise its only advantage is that its cleanable, but the oil from them gets on the maf and causes mpg to drop and run rich/lean and causes a bunch of issues, but you can clean the maf to fix that but those issues will actually cost you more in the long run instead of saving you money. i'd prefer the amsoil because it eliminates those issues because its a cleanable none oil charged filter, you can simply clean it with a vacuum cleaner. or you could also do the gotts mod and the K&N drop in filter will work nice with it.

 

Not if you are looking for an MPG improvement only.... I've got one of the K&N drop in ones. I've had it for over 7 years now... I've only cleaned it a total of 3 times too! Never have had a MAF issue.

My main reason for buying it was the re-useability of it... Also, with my simple cat back exhaust, it seems to have better throttle response according to the old 'seat O the pants meter'... I've run the paper filter in it while the K&N is in it's cleaning process (drying) and I swear I can feel it 'lag' a bit off the line.... Might be all mental, but it's been working for me all these years...

It gets ragged on pretty good here, as do other things I have on my truck that seems to work just fine for me, but others have had nothing but problems with....

IMO, between a decent 'tuned' exhaust and a free flowing air filter, mixed with a 'tune' from those tuner gadgets, that should get you the most bang for your buck.....

well i wont get the K&N but what else does autozone sell that is good?

 

not a whole lot

i think its like 15 bucks to do the gotts intake and you already have exhaust. btw is yours true dual or catback? which model cherrybomb?

 

catback..

im not sure what model?
i got it for a birthday present, its dual

 

cherrybomb makes flow through mufflers and chambered mufflers which is why i asked. it doesnt really matter a whole lot because a chambered muffler only robs a little bit of performance but the gotts intake should help you a noticeable amount. just look in the articles and how to section and you should find it in there.

 

where can you get this gotts intake? my exhaust it pretty damn loud would this intake do anything performance or making the truck louder?

 

its a do it yourself type mod. you can get the stuff from home depot or lowes and what not. its helps with performance and it will make the exhaust a little bit louder. i'll see if i can find it real quick.

 

well i have seen a do it your self intake but i didnt know if it was worth it or not? i think it is under How to's?

i'm pretty sure someone has dynoproven that it works good. maybe someone whos done it will tell you.
