Trowing CODE 34 after AVCR install? i have vpc.

[sportinct26]

Well I run into this problem a while back. but my car was parked in my garage for a while and now that i got the smog issue taking car off i will be able to test drive the car again to try to fix this problem.

MODS.
550cc with soppurting mods(pump/fpr/ss lines etc.)
Greddy IC, piping/bov, FFIM etc.
Big turbo
build engine, clutch etc.

^^ basically all supportin mods are present and accounted for.

ELECTRONICS.
its running of VPC/S-afc combo, and TT.

I run with this set up at about 20+ PSI using manual Boost controller and NO problem.

Then I decided to use a AVCR. and I CANT adjust the boost past 15psi. it seem like it hits fuel cut. but less harsh. AND TROWS CODE 34.

I check for vaccume and boost leak and nothing. I did all tune up. new oil/filter/plugs/etc.

any idea why it trows code 34 when i am using the AVCR and not when im using a manual boost controller.

I have check and double check the wiring and plumming for the avcr.

I just cant figure out why it wont let me adjust any higher.

is the AVCR not compatible with VPC?

If its a constant issue sale the avcr and pick up a less complicated ebc. I had an avcr in the car before I did the build and didnt like it so I sold it. Not worth the headache for me.

The AVCR must be providing a boost leak if it's not allowing 20psi while a MBC is. Either somewhere in it's system it's leaking boost or maybe you hooked it up incorrectly.
