To date, my running average with no mods has been
43mpg. All I did was fluff up the tires to 42psi cold, accelerate easy, short-shifting and coasting down hills <occasionally w/engine off> and coast in neautral up to red lights. I threw some tune up parts at it, but haven't checked the timing. Compression tested at 210, 200, 210psi.
Specs: '96 3 door, 1L 5-speed. All stock w/4.3 final drive. 2-piece Bra <to keep my headlights from sagging?> I just purchased the car 2 weeks ago, and have been catching up on the deferred maintainance for the PO

. Brakes, passenger axle assy, spark plugs, cap-n-rotor, O2 sensor, fresh GM Syncomesh trans fliud, tires, compression test.
I have been commuting 70 miles one-way. My route includes some slow-n-go traffic, plus about 6 miles of surface street driving with stop lights at every corner. But 80% of my 70mile commute is Interstate at freeway speeds. I choose 65mph, mostly as to not get run over during SF Bay Area commute hour

I took off the bra this morning... thinking it may be restraining better fuel economy, what a free feeling

Maybe less wind noise (or it's my imagination) Strange though, ever since removing the bra, the highbeams stay on. Should that get better when the weather warms up?... ok, I'll stop
Simply put, I want to average 50mpg including driving 65mph, 80% of the time. No hypermiling here, just smart driving technique and some sensable mods (maybe even a non-sensable mod or two) I don't want to slow down, pulse and glide isn't practicle for me, nor is removing the back seat <kids>, jack and spare or stripping out the sound deadening. I am even wrestling with adding ac and using it sparingly, or leave it as is with no ac. I plan a cam swap and degree, and maybe a trans or final drive gears swap this summer. Maybe an MSD box if I can get one from one of my race buddys for next to nothing. Maybe some areo mods like a grill partial block this week.
There is so much great information here, I can't believe my goal will be hard to reach.
