I then drove it on stock map +4.8psi coming on HARD between 2500 and 3000rpm. It is just too much torque for the FWD setup, there would have been over 400Nm in that sweet spot. It makes the car just too much mid-range and not enough top end. So now I use the custom curve and have a little bit of boost down low, coming in more progressively then filling in the region from 4000 to 5000 so it extends the torque curve a little higher and also fattens it up a bit. I took the JB1 off for service and the thing felt SO MUCH SLOWER !!
So it is definitely worth it but I would lower the boost from what the JB1 comes with standard. It is kind of fun using the mid-range torque when merging or on the highway. Nobody expect a station wagon to pull so hard onto highways or into gaps.
