yup, but i have zero engine mods. my tank holds about 4.2 gallons, the light comes on at 160-170 miles and i still have 0.8 gallons left(according to the manual) but i usually get gas at about 180-190miles. and it takes in about 4.0 gallons(although the manual says 3.8) when i fill up.
The 748 does about 145-155 before the light comes on, and its supposed to have about 1 gallon after the light comes on, i get gas in it usually at 160-70 miles. The 48 has carbon fiber cans. Going long distance(read all highway miles) the light on the 748 came on at 175-185 miles.
