How much of a drop in gas mileage should I expect when changing from my current mods(sig) to 60s and 2.8. Usually I get about 29mpg unless I am doing highway then its about 37mpg. I have searched a few gas mpg threads and seen anywhere from 18 to 50mpg....so I am concerned

I stay out of boost and never take it over 3k unless at the track

Thanks,

John

 

i have a 2.8, 60#'s intake etc. and i get avg. of 34-36 mpg. getting on it every once in a while.

btw royal purple oil deff gave me a few more miles to the gallon.

 

I got about 5 miles to the gallon more when I changed to 60's

 

Its all about the tune. If the car is tuned correctly you will probably see an increase in MPG.

 

31-32mpg crusin on hw
28mpg if i step on it

 

28ish maybe less

 

i get around 35-37 cruising on the highway at 80mph. in the city im looking at 26-29 and i shift anywhere from 2900 rpms to 3500 rpms. i get on it every once and a while too while maintaining those numbers.

 

Anyone notice an increase over stock when switching to stage 2 (stage 2 t00n as well)?

 

there is a thread on that

 

when i went to stage 2 i lost mpg. now that i have 60s and a kickass tune (thanks SJSchafer) i get stock or better mpg. at the moment my DIC says 29.2 mpg and thats a mix of city/hwy after 2 fill ups.

 

I think it is because stage 2 runs so rich.

 

Yah my gas mileage also went up when I installed my 60's and got a better tune.

 

I'm on the stage 2 tune, I only get like 22-24 mpg. that's all city though.

 

Thanks guys! I guess I can consider the 60s, 2.8, and my header/dp an inverstment...haha jk

 

My gas milage improved some!

 

My mpg rarely goes below 38, most of the time its low 40s.
60lbers do nothing bad for your mileage, and if tuned right, will improve it.

 

Sweet

 

just always remember, your right foot controls your MPG more than any other factor

 

Yeah I know the right foot control mpg, but like I said I don't go above 3k. Plus its fun to c peoples reaction when I accelerate slowly, I see all sorts of hand gestures and faces on the daily bases...lol

 

i get 29 mpg in the city being nice, and 25~26 if im tuning

 

33mpg city
39mpg highway

 

28 in the city and im always getting on it.....45 average on the highway for me

 

i call bs on 45mpg

how long are you usually driving on the highway for?

 

this was my average on a 60 mile trip from home to work a few months back.
I dont think hes bullshitting.
(P.S this was at 60mph, i could get more if i drop the speed a touch)

 

iv even seen in the 50's for a couple minutes.....if im on the highway cruisen at about 65...the speed limit here...i will do 45 all day long assuming there is no traffic and when im on the road there isnt any.....
