Yes, it shows to ECU pressure is less than in reality.

It's incorrect because ECU use boost pressure to calculate torque and load, that uses to other maps. For example to calculate gear shift points.

You are right. But JB4 declare +60hp, but RaceChip declare +98Hp. This is not a realistic result for a stock car.

I've never seen a serious result on a dyno or better on a dragstrip by car with racechip.
