Installed TBE, Lost power...
I would get an eflash from a tuner and see if that could work the knock counts out, and how accurate is the software you are using to measuring hp?
Maybe visiting a local dyno wouldn't be a bad idea.
Also what are program are you using for logging?

Not normal.

DLL claims 2-5% accuracy, but a 25HP loss is huge....
"ECU automatically reduces boost because of increased airflow if i recall correctly (the airflow part not ecu reducing boost)"
I don't see how you would be able to make gains by adding a TBE without a tune then?

Possible boost leak or other mechanical error?
I did a pass, logged it, went to my shop, threw my car up on my lift and installed the TBE, went back out and did another pass at the same location.
The car has 3410 miles, so i doubt anything mechanical...
No boost leak because it still holds 20+psi till redline, and there was about an hour difference between the two runs.

Dont forget that i have a Hallman MBC that bypasses the boost solenoid circuit so the ecu no longer has control over my boost.
I think you will run into some fuel cut issues with a tbe exhaust + mbc but no tune.
If i'm incorrect about that somebody please correct me (long day studying glia cells).

Since you installed the TBE you are hitting a higher load column with less timing in it, look at your timing in the log. Stock 9's hit about 1 or 2*, not -5 and -2
The 9 stock rom has alot less timing at peak torque in the higher loads, as you can see from your log. It quickly goes from +1* to -5*. That's a big change.
That is where your torque went. Same thing with up top with horsepower. Untill you can tune it, lower your boost and you will fall in the lower load columns with more timing.

Just because it holds boost doesn't mean you don't have a boost leak. You'll be making the turbo work harder to keep that boost level though.
Actually, it might send it out of its effeciency range....Let me go do a boost leak check...Ill be back in about a half hour....

Or should i just wait for my wideband? I only ask because it will be a minimum of a week before i recieve it. Also, after i add my fuel, will timing work itself out, or should i fine tune it as well?

Ahh, that makes sense. I was wondering my i had alot more negative values for ignition timing. Also, it is in this range where i am experiencing knock...I dont have a wideband 02 yet, but do you think if a add a small margin of fuel here, I will get rid of knock?

Also, i don't recommend you do ANY tuning until you get your wideband installed and learn how to use it and log with it. Then and only then, would i mess with timing and or fuel. For now, turn your boost down a bit until you can do some AFR logging. The knock could be a combination of lean AFR's and over advanced ignition timing for the boost pressures you are running(causing you to be in a load column thats not perfect for your engine/set-up)

Not only are you most likely in a higher load column(which will have less ignition timing on the high octane ignition map), you ran into some knock which also caused the ECU to pull out more timing, look at the timing on the low octane ignition map and see where you sit in that load range. That jump in ignition timing(retarded) will cause significant loss of power and high EGT's.

I only want to change the parameters that i can monitor, but i know a little fuel will help with knock...
