First-time log

Hey all -

2007 E92 auto, 93 Octane..

Current Mod list is:

BMS DCI
VRSF 7" FMIC
VRSF Charge pipe
Tial BOV
VRSF ******* DP
MHD STG2 tune

ordered parts:
Hexon RR550s
VRSF Inlets

Wanted to get a pre-new turbo log to see what was going on before making more modifications and blowing something up. Went WOT in 3rd gear from about 2K RPM to redline.

Trying to go through this log, but not 100% sure I know what I'm looking for. Can someone let me know if this all looks "OK" or if there are any warning signs I am missing?

Thanks!

You are getting some timing corrections.

How many miles on your plugs/coils/injectors and since your last walnut blast?

Boost is exceeded the target in the mid range. Cleaning that up might help some of the timing corrections, but not all. Looks like the tune might be a bit aggressive for your car/fuel. May want to contact Wedge about something custom.

Plugs are less than a month old (NGK 95770 gapped at 0.022)
I've replaced 4 coils over the last year, the other two haven't been replaced by me.
Injectors are all original (as far as I know, got the car at ~45k miles, ~114k now)
It's been about 30k since my last walnut blast

I'd definitely get a custom tune with the Hexons, you are seeing some timing corrections on the tune. 2-3 gallons of E85 would clean that right up I'd bet. However, I wouldn't exactly say your LPFP is 100% healthy, the pressure is low for pump gas, but still okay for now. I'd definitely look into the stage 2 lpfp for the hexons.
