Mk6 downpipe stage 2 power loss issue?

[Itsofficiallykyle]

Fairly new at this so I'm goona give this a shot. 2012 GTI DSG, CTS intake, R8 coils, NGK plugs, CTS charge and discharge pipes, beluga exhaust, COBB AP. Decided to get an ARM Dp and go stage 2 finally, installed it last night with no issues and turned to COBB OTS stage 2 93, and got noticable power loss in and turbo lag in low gears and low rpms, boost seems to be holding around 9psi without going complete wot. Decided to retune to stage 2 stock maf 93. Hoping someone can shed some light on this issue. Havent driven since going to stage 2 stock maf tune yet. Was stage 1 93 before and had no issues and got peak boost about 15psi. Any help would be great thanks

COBB strikes again!!

CEL? Scan it for codes. Are you using a spacer for the O2 sensor?

Also are you running the updated DV or a GFB Dv+?

Cobb strikes again . I do have a GFB DV+, I forgot to mention that. No O2 sensor spacers installed. Only code is for a high beam due to the bulbs I installed from De Auto which was unrelated.

As far as I know it should be that you weren’t on a “stock MAF” file so the ecu wasn’t reading the intake properly

So you believe that the appropriate ots map should've been the stage 2 stock maf 93?

Correct. The CTS intake utilizes the factory MAF sensor

I kind of figured, still havent driven it since I refreshed it to stage 2 stock maf 93 cause I was concerned about how poorly it was running after the tune. I really hope that's it, I appreciate the insight
