Finally installed JB4 on my 718
I installed it with the wireless kit so I could change maps on the go. There are 5 maps available:
Map 0: Stock power
Map 1: 2 PSI over boost
Map 2: 3 PSI
Map 3: 4 PSI
Map 4: 5 PSI
I have a base 718 Cayman, manual with Sport Chrono and PSE. Running it on map 4 I can notice a HUGE improvement on power. I have the chance to work for Porsche so I've driven every version of the 718 extensively. I can safely say the car on map 4 is equal if not quicker than a stock Boxster GTS.
The other thing I was pleasantly surprised to notice, the car produces noticeably more burbles and backfires when running on Map 4 than it did on stock.

If you can change the air filter, you can install the JB4. I've had it in for a few months. I'd really be interested to drive a 718 with Cobb tune. I wonder what the driving characteristics are. The JB4's power is more linear. You don't get that big punch of power like stock.

I had Cobb years ago on my STI but was never a big fan, and shipping the ECU was a deal breaker.
I've had JB4 on 2 cars and absolutely love it, I probably do a tune with E85 mix. I'll update once i receive the unit

If you want a discounted unit, I'm probably going to sell mine. Let me know.
