My experience with Stratified Controls was a long yet pleasant experience. I started my tune on a SoCal NATOR Dyno day with a mildly bolted MS3. After discussing my options with my Tuner, Alex, we waited until I had all of the upgrades installed before continuing. Once we started tuning, I had quite a few mechanical issues which Alex was able to help me with. I decided to go with a stealthy Smog friendly setup that involved a BNR Stage 3 turbo, a TMIC, Grimspeed EBCS, Stock exhaust equipment, crappy California 91 Octane, and the dreaded summer heat. Multiple revisions had to be made over a 3 month period since my setup was extremely difficult to tune. Every revision felt like Christmas morning and making the logs was a lot of fun. In the end, I had all of my mechanical issues dealt with and a quick spooling 30% E-85 tune with a tractable power curve that allows me to drive with confidence in the canyons but still have a nice punch in the straights (and slightly better gas mileage than stock). If I had to do this again, I would not hesitate to do this all over again.
On a separate note, get the Guardian Angel. Only a fool would drive around unprotected.
