Originally booked in for a custom tune, we had to call this one short, due to underlying issues that need resolving before the engine is going to respond correctly to the tuning.

Measured in 4th gear, these are the results from correctly applying exhaust gas temperature protection strategy to this Audi SQ5 TDI. The previous tuner had raised the limits to let the car perform stronger with a clogged DPF!

We do things right, not cheat. Slightly less performance, but safer for the engine.

This is the 231bhp version of the B48 engine. We unlocked the ECU, did the pre-tuning health check, then added a stage 1 off-the-shelf remap.

Measured in third gear, this engine gained 33bhp and 44Nm. The map should make 270bhp and 400Nm when tested in sixth.

Isuzu D-Max stage 1 remap from Haverhill. 2.4 seconds faster in our Dragy test is a respectable improvement for a safe tune.

We didn’t dyno test this one, but the estimated gains are around 30bhp and 60Nm.
