my boost keeps jumping around from 22 down to 11 back up then somtimes up to 33 and today i saw it go up to 45. is that bad? the fuel pressure is jumping from 15 to 14 then to 16 then back to 15 are they all suppose to stay in one number or what?

thanks

are they electric or mechanical gauges could be a short maybe ??

 

they are electric it is the commander the one they offer here on the site.

 

Make sure you have good grounds....might even be an idea to sand down to bare metal so that you know all the grounds are good.

 

Could be your tap wire for your boost feed.

 

ok the guage is working now but the boost when i am doing about 70 with the cruz on it jumps around when i am in idle parked it is at zero that is where it is suppose to be right? anyways when i am driving it jumps to 8, 9, 10, i have seen in up to 20 but i have never seen it stop and stay there. when i had the cruz on 70 it was jumping around 10, 11, down to 8 all around there. some ppl have told me that in wot it should be around 20-24 around there i have not seen that at all when i did that. ( dont ask how fast i was going when i did that, lets just say I would be writting this from a jail cell if i was cought) hehehe.
but at wot it was not showing 20-24 it was jumping around.
