What kind of mileage do you get?

[Mean Green]

how are you running 2200? I only run 2000 at 70.... 265/70/17 which is pretty much identical to 265/75/16


But I pull down a consistent 15 to 15.5 Hwy and have seen 17 when I was pretty much stock. Around town is 12.5 to 13

I posted that from my phone, meant to say 2100 RPM You get pretty decent miliage for a TBI!

Gotcha! I was going to say, whoa I am so confused I am fairly happy with it! for all my mods done I think I do well. I think my distributor is worn out, probably my next mod is a new billet one.

Best i ever got was:

City: 13
Hwy: 17

350 TBI all stock except air-lid flip and 31 inch All Terrains.

flip that lid back over, pull the tube out of the fender and silencer tube and really see some gains

Cant really think of anything else that could help out the MPG any more besides goin back to stock tires & dropping the truck back down.

NEVER!!! :XD:

Wow, I didn't expect to get all of this feedback... cool. Well, since I'm the OP, I might as well slap out what I'm on:

285/75/16 with 3:73's. K&N Filter (actually helped a little, to my shock and utter amazement) 1998 V8 350.

and kudos to the guy who gets 16.5 on 315's!!!! When I stick on 315's, I'll only dream of that kind of mileage. I'm getting worse than that right now! Maybe after I get a tune up it'll help. Does anyone have some simple mileage saving tips?*

*EXCEPT: being easy on the gas pedal. Who really wants to be told that?

Oh yeah- one more thing:

My folks have a 2wd '94 burb on 235's with the 350 TBI- they pulled 18.9 out of a 40 gallon tank on the interstate with 7 PEOPLE IN IT! That is a ton of weight- my buddy has a Ford Taurus and he only gets 21 out of that toting HIMSELF around!

18/20 for me when i had the flushmount on going to ky 75 and ac blasting I was up to 22.5 mpg 350tbi

100% stock - 15-18 mpg average
after heads, MPFI, cam - 15-17 average
after T56 trans swap using stock 3.73's on stock 29" tires - 11-14 average
regeared to 4.88's with same 29" tires - 15-16 average
supercharged running 6-7psi boost and 42# injectors - 15-16 average

all averages are a mix of city and highway in daily driving situations, pretty close to a 50/50 mix.

4.88s huh? deemn. I forgot to count the teeth, but I run at 120km/h@2krpm highway and 120km/h@5krpm city LMAO and before the sensors were fixed I could watch the needle go down a line with every WOT! Now that the engine's up to par, it's fairly decent for an L31 and a heavy foot. Just couldn't tell ya since my odo kicked the bucket, maybe 13-14 mpg.

 

[Aloicious]

yup, with 4.88's 29" tires, and in 6th gear I'm running just barely 2000 rpm at 70 on the freeway
