What gains in MPG with bolt-ons? How many MPG are gained from intake and exhaust bolt-ons? Also, underdrive pulleys should increase gas mileage as well. Does anybody think that all of these could increase gas mileage by 3 mpg or so in an A4? I need something to offset the loss from going with more gear, and it will help if I know that I can gain the MPGs back later on. Thanks in advance.
Re: What gains in MPG with bolt-ons? see sig for mod's
My car gained an average of 1 mpg in my normal driving. The car averaged 23 mpg before and averages 24 mpg now.
By the way, driving to Rockingham, getting in 5 passes in the 1/4 mile, the car still averaged 25 mpg.
Best mpg was 32.8 mpg on a trip
I think these LS1's are the best engines ever!

Re: What gains in MPG with bolt-ons? Your pretty lucky.....My car doesn't go very far, I average about 15MPG with about 65% highway.....Funny thing is too that recently I did sort of a test and drove my car about 150 miles on the highway at cruising speeds and whenever I had it on the street I kept it at below 2000 rpms.....So basically I drove the car about 200 miles with keeping it under 2000 rpms, obviosly sometimes I went over a little.....I averaged abot 18MPG <img border="0" title="" alt="[Sad]" src="gr_sad.gif" /> Oh well guess it'll just cost me more for gas.....

Re: What gains in MPG with bolt-ons? I got 19 MPG the last tank full city driving
with a 6 speed.
Thats with the SLP air lid & dual/dual I just got
ported MAF ends but won't know for a while how they change the MPG.
25 to 28 MPG I think u boyz are using new math
or something? <img border="0" alt="[bullshit]" title="" src="graemlins/gr_bs.gif" />

Re: What gains in MPG with bolt-ons? **** guys, i get 12mpg average on mostly city driving. My morning commute is 4 miles, 2 of that on the freeway. And i come home on city streets. Id have to admit, i do a lot of full throttle or high throttle driving.. So i guess this is my low point on the mpg scale.. I get usually 160 miles to a tank, with a little left in the tank at refill. When i drive upstate, all freeway, i can get 240 mies on a tank with a little left at refill. Hehe.. <img border="0" alt="[Fluffy]" title="" src="graemlins/fluffy.gif" />

Something is WAY off. I get like 25-28.
