After a few weeks of driving my 981 CS, loved everything about her, but knew I'd want to get a little more power mid-range from a tune...question is, which one? The options were dizzying as we all know. I also wasn't interested in headers as CA emissions are too strict.
Luckily I ran into @ICNU in my search, and he pointed me in the direction of Fabspeed + Cobb AP. It was great working with Fabspeed, the best customer service, very responsive, and did an awesome job with my tune. This process couldn't be simpler 1) install Cobb AP 2) datalog some runs 3) send files to tuning team 4) get tune, load Map, enjoy!
**note, drive 20ish miles hitting rev ranges in gears for the map to take full effect.
My car is stock, just a raw 981 CS / 6MT (vs. many reviews that are modded). A couple comparisons for reference:
Stock Map -> Cobb OTS Stage 1 Map
*This to me was obvious already, delivered more mid-range power, but still had some flat spots in the 2-4k rpm range, just less pronounced. Car felt livelier across revs. Sound wise, there was an added growl up top.
Cobb OTS Stage 1 Map -> Fabspeed Protune 91 OCT Stage 1 Map
*Good improvement with a snappier throttle, and all gears 2 - 4k rpms were more urgent going into the 5k+ revs. Smoother power delivery and my rev matches seemed easier to execute.
*1st - 3rd gears to redline are manic, esp. those last 6 - 7k revs. I generally feel like even in 3rd from 70mph, I can just tap the throttle and she'll surge forward unlike before.
*2nd gear - I can tap the throttle in lower revs now, and it's not as lazy as a transition from 2k - 4k revs.
Stock Map -> Fabspeed Protune 91 OCT Stage 1 Map
*Very evident increases, it's crazy how de-tuned the car is from factory. I recently did a back-to-back comparison for a smog check. The response is felt across all gears / RPMs. For example, 2nd gear @ 2.5k rpm - 4k rpm is a bog to flat spot, the ratio between throttle applied and tach response is off. With the tune, that waiting is gone, you snap the throttle, the car will surge / move with more urgency through redline.
*Sound wise, it gets even more growly across revs, and swear it seems the intake / induction sound is more pronounced just revving the engine. Vs. Stock Map, it convinces me I don't need another modded exhaust for a little while more.
For those wondering if it's worth doing on a stock car, I would say absolutely go for it - for $250 + any applicable discount on protune, you can't go wrong.
