17-19 psi...?!

Thats really nothing I would recommend if reliability is important for you.

Check with Terry at BMS...send him a log from your BT tool if you have...

enrita · 09-11-2009, 06:43 AM

Peak is useless, pull 4th and note how much you are boosting at 5, 5,5-6 K rpm.
You should be seeing around 15,5 sustained . Weather also matters.

Peak is ok, but it depends on where you are measuring it. Is this on a Rix gauge or off the TMAP?

Kevin@AKMotorwerk · 09-11-2009, 07:21 AM

do you still have your dv releasing to the atmosphere or did you hook them back up properly? if you wanna hit 18 talk to terry about an unlocked board for the jb3

i bet ur FMIC has a leak in one of the hoses... u called me and said u were gonna pass by cause u thought one hose wasn't on right... Seems like a slight boost leak.

branabolic · 09-11-2009, 10:58 AM

dont the cars boost less in the cold to keep power consistent? i know that is the case with stock software

It's basically impossible for you to sustain over 16psi with the production board. Are you just talking peak-recall? Maps 6/7 should be around 15psi sustained depending on weather and mods.

I was running on 12psi of boost for months on JB3 1.3 Map 7... eventually it crapped out and triggered CELs each time the car was restarted. It turns out the Solenoid and vacuum lines were bad according to the dealer. Now I'm boosting in the 16's after getting her back. I think it's a leak somewhere too, especially if you were seeing 18-19, and now you're in the 15's on the same gauge.

+1 im gonna reinstall the gauge/dv's and check the fmic for leaks with the hose's

Terrance28 · 09-11-2009, 04:54 PM

You will boost lower on a cooler night, but like others have said peak boost is useless look at your sustained boost and where your rpms are at.

I think you need the yellow springs

cn555ic · 09-12-2009, 10:24 PM

I see some oil residue on the bottom of the Forge DV where it connect to the grey connector...Its not alot of oil, but with all the dirt thats cake onto it, I see it more..Does anyone who have the Forge DV for extensive period have this also, or is yours clean without trace of oil to be found anywhere near the DVs?
