Psi

This is my first turbo awd car and I don't know if it's normal on the turbo eclipse engines that when you turn on thee car the boost gauge went to 17psi and the rpm at 800. Cause I bought the car with this modifications allready done so I don't know what I have to spect like normal.
I don't have mayor things done in my car (3" Exhaust, greddy Intake, K&N air filter, greddy type-s BOV, autometer gauges and a greddy turbo timer coming soon) I don't know if the last owner did something in the computer, I'm just telling you the mod. that I can see.
Thanks...

thats vacuum, not boost
its 17 In-Hg right?

I'm not sure right now, but could be, I can see that number from zero to the left

welll its vacuum, you cant have boost at idle anyway

only if you are a badass :)

only if you are a badass :)


hahaha :D

(welll its vacuum, you cant have boost at idle anyway.)
What that means?, cause I send the car to the mechanic less than 1 week ago and he said that I have problems with the idle or somethin like that,
I send the car to the mechanic cause the check engine line was on and he said this:"you have a weak signal from the computer".
What I have to do to fix that problem?.
And is normal the 17 psi?

again, its not PSI its Vacuum

K, let me break it down even futher

Vacuum is Left of the 0, and right of the 0 is PSI

vacuum cleaner / hairdryer
vacuum at idle / boost at WOT

Sorry you are right is vacuum I don't know why I call it psi.
well now I can make my questio in the right way...
Is normal that the car goes to 17 of vacuum when is on neutral???.
And about the idle and the computer (what the mechanic said) any suggestion????
Thanks and sorry about my ignorance!!!!

If I recall, normal vacuum at idle is 17-22 inches of mercury, Hg.

It's strange I can only made 100 somethin milles per tank, that is normal?
I admit that I'm drivin always fast but I think that is drinking to much :0, that hurts in my pocket :)

Well I have a gst and I get about 26 mpg highway, roughly 270 miles per tank. I think you have a problem if you are only getting 100 miles to the tank unless you have a 9 sec. car or something.

thats bad,
to give you and idea. I usually get 100miles on the first 1/4 tank
and about 300 to the tank
and i'm running rich

I don't know what to do?
I think that this in not a 9 sec car, but I never try it :)
On monday i will go to mitsu dealer ship to charge my a/c system, maybe I will ask them and they can check what it's wrong.
I think that the last owner tooks away the cat flow, that is not good (legal) right?, but that could'n be the reason of my gas/milles problem!!! I guess so :)
