Boost Issues

[rotary boy]

Hi,

I have no boost, it has literally vanished. I am wondering if it might be the map sensor. I did a test on the commander and it told me the following:

PIM 2.63
VTA1 0.63
VTA2 1.36
VMop1.26
WTRT 2.00
AIRT 2.64
FUEL 4.06
OS2 0.03

NTR, CAT (removed) AWL, PAC & CCN were blacked out squares on the display.

Does any of this suggest a Map sensor problem. I have been told to check the boost pressure/vacuum at idle using a commander? Again I am not too sure what I should be looking for.

Can anyone help me out with this?

Check your turbo outlet pipes. Early cars have a coupler that likes to pop off. Later cars switched to a hard style 2 bolt flange.

Watch your PIM, if it does not move when you rev the car your MAP sensor could be unplugged. Also look in the boost settings table. What are the values? even if they are zero you should still be making spring pressure boost. To have zero boost you must have a boost leak.
