Did you pull logs to see this, or look at your boost gauge? Is your downpipe catless?

So, I'm on the stage 2 COBB OTS mapp with an invidia high-slow catted DP. I've recently been realizing im boosting 20PSI at some points. Should I run the Low WasteGate map, and will this solve my problem??
When you hit 20psi, what do oyur AFRs look like?
Just because you are hitting 20 does not mean you actually have a 'problem' exactly. If your ECU is compensating with added fuel, you are fine. If you are running lean, or gettign knock, you have issues.

It's probably not boost creep. To test for boost creep, you would have to force your wgdc to zero (mechanically or in the ECU). For now, try the lower wastegate map. It should help.
Otherwise, contact Cobb.

So to further inform you guys, I'm using the cobb AP on the boost gauge to see what boost im hitting. And also, I do not pay attention to AFR, because quite honestly i have NO idea what numbers to be looking for (putting flame suit on)
This isn't directed just at you, Mike, just in general, but I don't understand why anyone would bring up an issue with tuning without supplying a datalog. That said...
Try the LWG map from Cobb. If you're still overshooting, try the SLWG map.Originally Posted by Heide264
^^^ +1.... Initial stage 2 OTS map was ..... speechless. The boost spike was beyond the boost gauge and settled near 20psi...
The stage2 lwg map spiked to 20psi and settled back down immediately to 18psi which is fairly close to the target boost of 18.5psi for 2013 wrx...
So. Do try the lwg map
