Evolve Tuned 435d with before and after CSF Intercooler Install/Dyno

We have tested CSF's N55 intercooler before on an F87 M2 with impressive results, but CSF recently informed us that it will also fit the diesel models! We were keen to see if the intercooler would have such a prominent effect on the diesel platform.

A customer came to us with an F32 435D to have a remap and the intercooler fitted. We first applied our ECU tune to get a baseline figure, then fitted the CSF Intercooler to see how much difference it would make to a tuned car.

Unfortunately the car was fitted with winter tyres so the headline figures aren't what we would expect, but as the test was done on the same tyres the gains are valid.

So how's the lag in daily driving and associated drop in fuel economy with the N57? That's what turned me off from the CSF with the N47. I have no complaints about the CACT/IAT performance of the CSF intercooler, but the daily driving characteristics of it were annoying.

No noticeable lag. Can't comment on the MPG as have not looked at it yet.

That's good. Maybe the different exhaust pulses of the 6cyl engine are helping the turbo spool more quickly?
