    ExperTune for 2008 Porsche Cayman S

    Posted by David Bridges on 6th Aug 2020

    I recently purchased Fabspeed Sport Headers, Sport Cats, Maxflo Exhaust and IPD Plenum. Obviously the result was a giant grin across my face when I cranked my car! It did cause some check engine lights which did not surprise me considering all of the extensive upgrades I had done. I purchased the "tune" to bring it all together. After installation I've not experienced any lights and the the car runs very smooth. I would say it's the final step to realize all of your new found horses!!

    987.1 Fabspeed Tuning

    Posted by Dean Roussel on 21st Jul 2020

    Just did the Fabspeed tune to my 987.1 Boxster. Wow, you can feel the difference in the seat of your pants! Throttle response is greatly improved over factory. Feels more "torquey". Scott Keating and the tuner(s) at Fabspeed were awesome to work with from start to finish. Would highly recommend!
