I installed my downpipes a week ago and last night after driving like 20min doing a steady 70 I got half power. I pulled over cleared codes and no problems. Drove to work today and got same code. Just on the way home not the way there. Its Code 12544 and 12543. I updated firmware and maps on procede. Any suggestions guys ? And datalogs look great boost holding to 5800 rpm and then slowly tapering down. Thanks tim

I've seen a case where the v-band on the downpipe was positioned in a way that interfered with wastegate motion. This caused a limited boost condition that was plaguing the customer for weeks. He ended up replacing solenoids, hoses, bypass valves. When it was just the downpipe clamp that needed to be rotated.

Just make sure this code occurs on public release maps (and in valet). And that it started after the dp install.

Ok ill def look into that. What's getting me is I can be at full boost have a great looking data log and get no codes. The only time I'm getting them is running low boost map 1 12psi doing 70 and get them. If it was a v clamp I feel like id be getting them everytime I got on it.

The map settings will not contribute to the problem if you are getting the code while cruising. Just make sure you are runnin the public map/firmware (2-23) and not the private beta maps/fw that has been floating around.

Its not the procede shiv I know that. Procede has not given me a problem since I put it in. Was just wondering if anyone on the forum encountered the same problems after dp install ill go down there tommorow n re tighten everthing.

Can an exhaust leak at the turbos cause this code ?
