I did not calibrate the wastegate after IS20 install. Since it was used I was hoping it would be OK. What do you mean by safety? How can you tell by the graph?It looks like your safety is off. The problem could be related to calibration of the wastegate actuator?
The car feels faster but not much low end. Probably due to larger turbo. However, I expected a more significant increase jumping from IS12 to IS20. To be honest I don't fell much of a difference between running Map 4 and this Map 6.
