Default Please look at my logs - 03 wrx (5 logs inside)

ej205, 138k, invidia catless dp, borla catback, k&n drop-in to stock airbox, walboro 255, AP stage 2 93 octane LWG map (changed to LWG from normal because i was seeing some overboost in the 19's - the LWG helped only a little).

Log #1: Third gear:
https://drive.google.com/file/d/0B4I...ew?usp=sharing

Log #2: Also third gear (pull right after the one above):
https://drive.google.com/file/d/0B4I...ew?usp=sharing

Log #3: right after log #2 (3rd gear - little overboost):
https://drive.google.com/file/d/0B4I...ew?usp=sharing

Log #4: SECOND GEAR (also overboost):
https://drive.google.com/file/d/0B4I...ew?usp=sharing

Log #5: 3rd gear (again with the overboost):
https://drive.google.com/file/d/0B4I...ew?usp=sharing

Also, it seemed like I was hitting right around 17 like the tune calls for only when I went wot around 2.5k rpms... When I stepped on it around 3/3.5 it seemed to creep more.
Thanks in advance - car has been running well, not burning and oil, etc but I want to listen to what you guys have to say.

Car seems to be generally running well, although you started to register a bit of knock around 4900 RPM starting from log 4 after you did continuous pulls. This is most likely from heatsoaking the TMIC. If target boost is 17 PSI, then the most overboost I saw was less than 1 PSI even when you went WOT from ~3200 RPM, so I wouldn't be too concerned about it.

Aside from the small amount of overboost, I'm not seeing any boost creep (when boost continues to rise even with zero WGDC).

Thanks, I'll look into buying an sti intercooler (assuming that's how you fix the tmic heatsoak). I think the jdm ones are the ones with less hassle - if anyones selling one hmu.

Could the overboost be due to an old ebcs? I have a cobb 3 port ebcs on the way and was wondering if that would help with the cobb ebcs map.

Solve the heat problem at the source: turbo blanket (ots or diy) and heat wrap the top third of the DP. If you are feeling frisky, wrap the Up pipe, too. Bang for the buck.

I just replaced my old BCS with new OEM and it helped my spool for sure, but I still overboost 2-3 PSI on a stock tune & stock DP (but catless UP and PnP exh bits). Gonna check my WG preload and WG function (pressurizing it to see if the diaphragm is sticky, leaky/bad).

GL man.
