Alright.. My Sti is cobb stage two with damn near every bolt on less of a turbo upgrade. Today I got a muffler shop to rig up a 3" pipe that I could bolt on to my muffler section for racing so I could just run open pipe. Well I put that on and drove down to the gas station and filled it up with 100 oct and switched my map to Stage 2 93 oct with a real time map of STU 100. Went down the freeway and it felt like crap so I plugged my accessport in and I am only peaking out at 15 pounds of boost. I went back to the house and unplugged the battery and let it sit for a bit then plugged it back in and ran the STU 100 map again and still only 15 pounds.... Anybody got any ideas?

 

What boost are you seeing on your normal map? That would tell you if it was a mechanical problem or just a bad STU100 map.

 

I was hitting in between 18 and 19.. Somewhere in that general area.. But yesterday I took off the pipe and put my muffler back on, then I tuned it back to stock, disconnected the battery for a while then tuned it back to stage 2 93oct then did the STU 100 real time map and its running like a savage now.
