you gotta be kidding me! Stock M6 LT1 and the best I've gotten was 24-25...

 

I was BABYING it!

 

before my 306 i would get 17-18 in the city and 29-31 on the highway with my M6 and 2.73s

with the 306 i get 15mpg in the city and 27 mpg on the highway running rich from Florida to New York

 

how the hell do you guys get those kinda mpg.. i get like 12-15 with a barely modified car

 

so was I! Shifted at or below 2000 rpms and 70mph on the interstate.

 

No clue then?! I was going between 65 and 75 from WV to NC.

 

mine has more mods than last yr when i posted on here, still hasnt been tuned, and still gets 13mpg. lol. and it is STILL sitting. only a few more parts to go and then it will be tuned in about 2 wks

 

That explains your user ID then (possibly)...

I've only had my TA for a few months so there's a good chance that it needs new plugs, fuel filter, and O2 sensors...that could very well be the diff in mine.

 

I just noticed you're in Akron, OH...I don't know where you're planning on getting your car tuned, but there's a LT1/LS1 whiz in Ashland, KY...there are plenty of guys that drive from the Louisville/Lexington, KY areas to have him tune their cars...probaby a 2-3 hour drive for them, but you're probably lookin at 4 hours or so.

Check out www.kyhorsepower.com and ask around...his user id there is bluecat. 606 571 6334 or philliphsmith@windstream.net...you will not be disappointed...tell him silver97z from kyhorsepower sent you...
