Was this for me?

yes, or anyone in general. You asked about the log sharing so I thought maybe you were having a problem and were looking for help.

I'd just like to share something interesting I've found... I've switched to Cobb now, in part due to their spark based traction control and how apparently it works some magic for 2WD cars.

Here's a log of wheelspin with OEM traction control back when I had my JB4:
https://datazap.me/u/ashiun/oct-14-...ty-wheelspin-rain?log=0&data=1-4&zoom=246-312

And here's one with Cobb's Traction control set on allowing 30% slip. I deleted most parameters per my tuner's request to not share logs publicly:
https://datazap.me/u/ashiun/cobb-tc-3-wheelspin?log=0&data=2-3

Both logs I had my foot flat on the throttle. Looking at the logs, the Cobb seems magical at managing wheelspin and maintaining boost, but it could be the case that the OEM TC run was simply in worse conditions and exaggerates the results.

You have to code all the OEM TC off for the Cobb TC to work, right?

I'm still not sure on how exactly Cobb TC works. I've seen people say that you have to code OEM off. However, my tuner also told me Cobb TC is always on.

I had it on long hold this run (ASR off, ESC Sport). I also don't see why I need to code ESC to completely off, because ESC shouldn't interfere with traction control, that's ASR's job, which is already off without coding.

Confusion between ESC (stability control, aka keeping your car straight) and ASR (traction control, wheel spin) aside, I suppose with OEM TC on, Cobb is also on but OEM overrides it. I suppose it's possible that what they mean is coding TC to completely off in case the OEM "off" setting isn't truly completely off.

ESC is supposed to be set to off

Hey guys,
This is my first time tuning and my first post!
I am a little concerned with some of my logs.
I have a 2015 GTI SE DSG I always put in 93 Octane.
I am currently running the MAP Stage 1 tune v2.2
I am completely stock except for a K&N Drop in filter.
I have let the car adapt to the tune for over 200 miles.
Is it safe to have my boost pressure at 21psi at 6300 RPM with no other mods on 93?
Also is it normal to have the boost dip in the beginning of the pull like it does?
Finally should I be concerned with the amount of KN and timing I'm pulling?
I planned on going back to stage 0 and doing some logs to see if similar things were happening and maybe switching to some RS7 plugs. What do you guys think?

The boost is a bit up and down, that is something that could be smoothed out so it's a bit more consistent and linear, but I wouldn't say it is a problem in that it'll harm the car. It might just affect the drivability. The boost changes are fairly minor.

The timing being pulled is a towards the high side, and is present throughout the RPM range and doesn't appear to recover. This is something that i'd recommend watching as it could be an issue and something you'd want to get cleaned up. I do not know if MAP offers revisions or custom tunes or if you want to stay with them, but I would suggest having it looked at.

I have been holding off going APR for a while now, due to COBB stating that they are close to a DSG tune. I keep checking their site but no new updates :-( Does anyone have any idea on time frame? If I gotta wait another 6 months I'm just going to jump ship to APR, but if its close . . . . I'd love to go with COBB.
