Anybody running 07's catless with cobb ots stage 2 map? Im installing a catless downpipe on friday and gonna just flash the cobb ots stage 2 map untill a get a pro tune sometime next month. Ive read about the boost creep issues with the 07's. I ordered the larger restrictor pill from subaru, i heard that helps with the boost creep.

 

The pill might help but generally it's kind of common to have boost creep issues... It's kind of a hit or miss. You might have issues, you may not. Good luck with the install.

 

Thanks I hope everything goes smoothly. What about an aftermarket boost solenoid does that help?

 

On my 07 sti im running cobb catback with a catless nvidia downpipe on a custom stage 2 map provided by gst motorsports. I have no boost creep, also when I was using the AP stage 2 OTS map I didnt have any boost creep. I think you should be okay, just make sure to get a tune if you do.

 

Boost creep is a mechanical issue. I would highly recommend getting a protune since you have a 07 sti and see if that helps. Your tuner should be able to play with the waste gate duty cycle.

Im hoping for no boost creep at all. I'm definetly getting a protune but I'm gonna have to roll on the Cobb stage 2 ots for a couple weeks.

 

By the way what kind of numbers did you get after the gst protune? And what kind of mods do you have? I'll be runnning a greddy ti-c with a titek catless dp

 

I went to GST to get my tune from Mike, I put down 267 AWHP and 292 Torque on pump 91 Gas. Keep in mind the GST dyno is called the "heartbreaker" other dynos would of read a little higher.
