I went for a quick drive today on an empty road with the OBD and torque app running. Drove the vehicle sedately until it reached the optimum temperature and did back to back high speed runs. These are the boost figures shown as per torque app when brought close to the redline with the pedal floored. Please correct me if I am wrong: Boost while idle: 0.1psi
1st gear:21.9psi
2nd gear:18.5psi
3rd gear: 16psi
(The whole drive was with AC off and only me as the driver.)
How can a stock engine with no performance upgrades show 21.9psi which is higher than your remapped one? Is the device or the app at fault?
Also it showed a boost of around 12psi in 2nd gear at 2.5k rpm
Now speaking about the experience, never felt something like this actually  . Wheel slips when shifted from 1st to 2nd at the redline. The pull is felt only after 4k rpm in1st gear. The pull felt in 2nd gear doesn't last long. The acceleration is linear in 3rd gear. Used to drive all these days with the AC on, so maybe I never really felt the true potential of the 1.3MJD.
I also got some EGR commanded% figures. (I know nothing about this) 1.96%at idling
54% while driving
