The MAC valve based EBCSs (all aftermarket except CS) and the Corksport one all use similar parameters. However, although there are some maps for a grimspeed EBCS, the calibration values are not ideal. But in your case this is not the problem... if anything you should feel the car being too twitchy ...

For the next logs please load this dashboard preset on to your versatuner (Dashboard -> presets -> import and then load): https://www.dropbox.com/scl/fi/s7e5zpu3htv3rqcftjz84/Full-3MPSBL-Logging.vtpre?rlkey=ozr0n7md60b3c26fy54g5ufnb&st=gzbmrf04&dl=0 If you are still on the factory boost cont...

I can help you with that. Please export the current tune you're using and send it to me in a direct message and I'll send back to you a modified version. I can also make variations for you, like altering the RPM the pops calm down, even get you back the engine braking ability.

Well, it's the same thing basically.
And yes, I would remove it... in case somehow the throttle calibrates when the tune is flashed and it will not want to get tricked any more...

Since you have access to the throttle tables you can tune the throttle response from those and not use any external device. When you removed that throttle booster or however they call them, the APP/throttle mappings came back to normal.

You can always compare your tune with the stock tune, or create a new stock tune and look at the factory tables.

Fix that and check after... things will be different.

Those pops are most likely caused by the residual fuel which is shown by those relatively high negative LTFTs...

I really do not see any abnormal behavior in this log, but I agree that from inside the car things may feel totally differently. There are two things that caught my eye though: 1. the intake manifold is incredibly hot. the coolant temp is in the low 100C and the intake manifold air temp is in the hi...

In this log you revved the car stationary... it's really hard to figure out anything from such a log with 500+ rpm increase per log line. And yes it is normal for the ECU to command 100% ebcs duty when you press the acceleration hard until the desired targets are reached. If the car driver and react...
