Thumbs up procede v2 limp mode

I am running rissracing dp's and burger air induction along with the v2. with the new maps 2 26 08 I had to decrease the torque to 50% at 6000rpm's and o% at 6500 and above.or I would get limp mode. Is anyone having the same issues. I installed a boost gauge to see if the data logs boost was accurate, the datalogs showed boost form 14.5 to 14.9. unfortunately the digital boost gauge is showing -5.0 psi at idle . with this adjustment a boost pressure of 10 showed be approx 15 if my calculations are valid.

You will see negative boost at idle on your boost gauge. This is because it is plumbed into your intake manifold, not intercooler pipe (which is where the TMAP sensor--what the PROcede reads/logs-- is). So I'd imagine that it is reading just fine. If you are dropping UT at high RPM, boost is probably tapering off to ~10psi above 6000rpm.

Our own car is running catless. And no, it doesn't trigger any CELs. Update kits for v2 users should be ready to go within a 2 weeks. If you're local, maybe sooner.
