I have recently fitted my new fmic and pipework and have noticed that the needle on the standard boost gauge does not go to the edge of the scale anymore. is this just a case of setting up my boost controller again (profec b spec 2)?
thanks

FMIC cud be causing a bit more lag, maybe the needle wud hit 1bar eventually?? Although the needle on the standard gauge does'nt show 1bar.

at 1bar, the needle on the standard gauge should go off the scale. i thought it may be lag but then as i accelerate and come on boost, the needle is staying on the scale and not making full boost

What does it goto on the standard gauge? Plus what does your boost controller read?

it goes to about 5 on the gauge (whatever the units are). my boost controller was originally set to 1bar by ian at hiteq and i darent fiddle with it. i know the controller gives boost reading in real time but i havent checked what it reads

I would check to see what your controller is reading in real time mate, then if it is reading low, make sure it hasnt been fiddled with, as it shouldn't change boost levels. Have you checked all the hoses are connected again properly? you might be experiencing boost leak or something:?

yeh im assuming all the boost settings are the same as before i fitted the intercooler. i will have a check what the controller is reading tomorrow and see everythings tight. cheers mate

Hey mate, odds are the frontmount has cooled your inlet charge making it denser, and therefore dropping the pressure in the inlet manifold where your boost guage sender is fed from. If you measured the pressure at the turbo it should still be the same as before, it's just you have a more efficiently cooled charge after the cooler (plus prob a wee bit of lag).
;)

after checking that all pipes etc are tight and theres no leaks, i remembered that i had moved my boost solenoid into a slightly different position. i have included a piccy and as you can see, i had a plastic cap in the back of it. i removed it and now its boosting like it was and all is fine. does this seem right??

The standard gauge reads in millimeters of mercury (mmhg) and it goes to 700mmhg iirc.. that equates to 0.93 of a bar.

Yes the instructions say remove ALL plastic plugs from valve unit.

i think the way the solenoid was fitted, the plug may have been half in half out sort of thing so was still bleeding air off. when i repositioned the solenoid i pushed the plug fully in. removed now and all is well. at hiteq tomorrow for some things so i'l get it checked. cheers
