Ok, so it's reading inches of mercury vacuum. 0" hg = 14.7 psi map, 30" hg = 0 psi.
Vacuum Pressure - Converting Units (compare PSI and Inches Mercury Gauge)

You want to accelerate around 5 on your gauge (but not below 2-3), at the border of Poor and Fair. It sounds backwards, but your engine makes power more efficiently with an open throttle and low rpm. Make power and accelerate efficiently, then switch and keep the gauge high for cruising. Don't go above 2500 rpm or so. I prefer shifting at 2000.

Timing question??

I did a quick check over and re checked my timing
My timing is at 11* on the red mark and that is with the distributor all the way rotated towards the front radiator.
Is the red mark the correct mark??

Engine at temp fan kicked on
Jumped timing connector engine light came on

The red mark is the one in the middle of the three clustered closely together, and it should be at 12* ... what makes you think that mark is at 11? I have heard that the problem may be with the timing belt itself. Have you replaced it? Are you sure it is installed correctly?

My timing light has a adjustable dial on it and I set it at 11 and its right on with the red mark.
My belt was change before I got it at 123k miles. ( has a tag on the fender)

So with it being all the way forward and Set at 11 is that good or?

When I first got it the timing was set at 12* on TDC white mark and was only getting 25 mpg

Something seems wrong with this picture. The lone white mark on the pulley is not 12* ... it is top dead center. I think something may have been wrong with the belt change. The Honda Service Manual designates the red mark as 12* ... you need to check this out further.

Hey man, I wouldn't trust the dial on those gauges, just set out gun to 0* and line it up with the middle dash and you will be good to go! grilles blocks are awesome an dpi the bumper block is excellent too, just leave the part covering the radiator open a little. I got like 3-5 mpg from te block offs. I heard holes on the air box is good too. I have an after market intake but if I didn't I'd deffinetly do the holes. Also I just did my pcv. When you did yours did you change the rubber grommet? Mine was hard as a rock and leaking oil everywhere. Made a huge difference. And for te sea foam. Did you do the intake manifold treatment by slurping it up through the brake booster line? I'm about to do that because my intake is dirty as a mo fo. Also since you are lowered you should also go to Home Depot and get some garage door trim or lawn edgeing and make a front lip. They look super cool. They're cheep, they help milage and they don't get broken on the ground. You can't loose. And lastly belly pans are sweet. It's voting season. Go grab this election signs before they get thrown away!

Thanks for the reply. I have experimented on the timing. I set to the middle and I have recently got 32mpg now I went up to the left side mark of the red mark. 14* and seems to be running a little better.

When I got 32 mpg on the last tank I raced my wife in her scion xb home from the mall it was about 10 miles freeway and uphill. So I prob could have got easily 35-40 maybe

How did u do the lip. It looks cool.

Also do u have a pic of the grille blocks you did.
