Blame your car for not bringing fuel trims back on sooner.

to the OP. the Comp G has 3.29 gears vs the GTP's 2.92's... this will hurt HW mpg and may help in town. the gear swap helps low end acceleration.

How do I get my LTFT with my scan gauge?

Pretttty low.

i just filed up and re set all my dic and trip, going to see what #'s i pull.

will let you all know how it does.

well i went through 11.78 gallons of gas, and only got 192 miles. the math says 16.2 mpg avg, the dic says 17.8. off by 2 mpg.

this is a good mix of a 1 mile drive to work, and 20 mile highways runs that are all hills.

What type of gas are all you running? i get a few MPGs better when i run premium.

93 octane, all the time.

don't use 87, its bad for your engine if you are s/c.

if n/a knock your self out.

93 octane in my 1997 sc gtp and I get 26 -27 mostly highway

Ive been on the same tank in the gp since sept.

^^ you're cheating. it's because it's brokeded.
