Gas mileage with tbi

[moturbopar]

with my 91 suburban 350tbi/700r4/3.42/and 31s on my last fill up i went just over 600 miles on one tank (40gal). so whats that about 15! Its so much better than the old blazer at 10mpg.

some of you guys REALLY need a tune, and a lot of you need to regar to compensate for larger tires. my K20, sitting on stockish sized tires, TH350, 203 in Hi-Loc, and 4.10 gears gets 12mpg... with a 7.5" snow blade on the front, PUSHING SNOW about half the time its out. the key to milage is putting your engine into its powerband, rather than trying to keep the RPMs low.
