Here we have James' BMW 335 XDrive in for hardware fitting + Stage 2 ECU + TCU on the dyno
This had an Uprated Intercooler, brake discs and pads front and rear, gearbox service, engine service.
Once all of this was done, onto the dyno we went to see what we could get out of it.
With this being XDrive we had to use a software called XDelete which allows you to switch to RWD on these models, This allows us to run the vehicle up to see what it is making before and after the tuning session and then switch it back to xDrive without any issues.
With this still having DPF in place, it did limit us compared to a Stage 2 that would have a DPF gutted or a downpipe but James wanted the extra power whilst retaining the road legal side of things (I don't blame him lol).
We also carried out our Stage 2 TCU which improves the gearbox massively including: Torque limiters raised to allow for more torque to be produced, Gear display, Quicker shifts, Clutch Parameters, Oil Pressure Management and to top it off some nice torque punch on upshifts when giving it some beans!
This made some pretty solid figures and a WHOLE bunch of torque which I'm sure will be enough for James!
