p0299 supercharger/turbo boost low

[Dzchey21]

anyone else run into this on tuned 12s with aftermarket turbos?

I cant seem to get rid of the code no matter what i do with the tuning.

Haller found a TSB on it for stock 12s built before 5/16/12


Any help would be great.

Thanks,

Not sure if this has been gone over or not, but have you tested your MAP sensor and the wiring going to it? Im not sure which kit you got or if you had to move/mess with that sensor at all. May have got damaged in the swap. Just seems weird that no matter what you do with tuning, it doesnt go away. Could be a physical part rather than tuning.

its reading map smooth and with no issues.

have you talked to matt or tadd or Bentley ? there are plenty of earlier 6.7 running aftermarket turbos without that issue.

I know which is why I'm wondering if the 12 tsb for the code is my only problem

I've talked to Tadd and Bentley but I think he's a sema so no response from him yet.

Been working with Bentley on this one and he added some tables today that i think might cure this problem. Got a tune loaded now hopefully tomorrow i will have some results. This -0 weather doesnt have me overly motivated to do any testing LOL

After talking to bently it sounds like once you turn that off for a single non vgt these codes and perameters go away with it. On aftermarket VGT im not positive how they are not throwing codes unless there just arent that many out there. And this may fall back into the 12 TSB thing. I think i have it corrected but ill update tomorrow.
