I can fix that for you for free. All you need is a Tactrix cable.

Just ask Eyler, he did it in like 10 minutes earlier today.

P0140 has nothing to do with a bov whatsoever and nothing to do with having SST.

It's rear 02 from having no cat and easily taken care of (Thanks to Tephra) with somebody that actually knows the ECU, like Golden stated above.

Turn off your Rear O2 in the Ecu Options. Do P0140 and P0139 disables.

So that fixed it for good? Same thing happened to me after tune, P0140. Never had it for a year running test pipe with Cobb's OTS maps. Rear 02 is unchecked on my map with the AP. Looks like I need do this, hope it works.
