Tired of the smoking..

My 2009 MS3 smokes intermittently at idle. It has been doing it for about a year now. I have tried just about every fix (thicker oil, banjo bolt, pill) and none of it makes a difference. My mods are..

Injen Intake
CPE Rear Motor Mount
Hypertech Tune
MBC set to 16 psi (Hypertech tune only runs at 12-13 at my altitude because of the ECU not adjusting for pressure drop. Stock it was running 12.5 PSI at 6000ft elevation.Yea..)
Exhaust shop test pipe
No resonators
Meth Injection
DIY Intercooler Sprayer
FMIC core awaiting delivery of piping kit

I really am just tired of having to modulate the throttle at idle to keep it from smoking. If I hold it at around 1k idle no smoke. I know the AP can change this, but that would require dropping more money and selling my Hypertech. I also wouldn't look forward to learning how to tune, or paying even more money for a pro tune. OTS maps are not something I want to risk because of how different this car runs at high altitudes. In the next year I will go with a stage 2 BNR and be done with the smoking but until then I would like a temporary fix. It blows that hypertech will not put in a simple option for a 900 or 950 rpm idle.

Should I just sell the Hypertech and use that money to partial fund a used AP and only use it to control boost and idle until I can afford a pro tune or is there anyway to "trick" the ecu into raising the idle similar to a map clamp? Thanks.
 
I'm not familiar with Hypertech as I have an AP but I don't see why the AP maps would be more risky than the hypertech? As far as I understand both use "generic flashes".
 
...ain't you had enough issues with the AP to stop recommending it yet? (naughty) ...not to mention the smoking turbo....

HT used EGT to monitor the destructive tendencies of atune. This is safer than tuning off AFR, especially with a pinner turbo like this. The EGT temps skyrocket at high revs, especially with maintained high boost after 5800 or so. Hence, HT tapers the boost level off to keep those temps down.
 
My turbo smoking like hell too...I have both cattless with thicker oil,oil catch can and pill. But when I put the stock test pipe with Catt it didn't smoke nomore that's how I passed my emmision!!!
 
Yea im think at my altitude I might be able to get away with getting a BNR (stage 2) and running it off the Hypertech tune. Im down about 30-40 hp from sea level. I'm tired of the smoke and the K04 so hopefully this spring I can get rid of both and be done with it. Ive driven with it for so long that I always use my right foot to manually adjust the idle to around 1200 rmps to keep it from smoking. The bad part is I find myself trying to do that in other peoples cars now...
