Thread: Tuning 2014 D4 3.0 SD

When towing?

Have to agree. The D4 should lug anything anywhere with considerable, nay, immense ease. Spend the money ON the race car, in my experience.

I suppose that would depend on the tune. It would be nice if you could tune these (or any modern vehicle) to suit your requirements. i.e. Towing, Highway, Town, 4wding etc.. I had three different engine and three different gearbox flash tunes specifically tweaked from data logging for my 6ltr Sportwagon.

You mean like the towing mapping in the 3.0l that changes shift points etc when towing

The 3.0l will tow 3.5t at speed up almost anything.

Has anyone seen Roothy's 'real world test' in a 75 series cruiser on the Gateway Bridge, measuring EGTs and acceleration with stock, tuned, exhaust upgrade and both? He certainly showed the temps getting up more without the freer flowing exhaust, but ppl seem to think the D4s and presumably RRSs have pretty good stock exhausts?

ive had mine Tuned by Superchips NZ, Awesome Performance and Fuel consumption is great, with an average of 9.1l per 100!

Someone i know did the 'real world' test on the gateway bridge in an Audi 4.2,had to back off as it was winding off the speedo before the top

No need for a tune..

False Alarm.
