Thread: V8 Bruce Davis chip upgrade

I believe it was the same dunk both times as was my understanding (now I may be wrong here) it was done by Davis before and after it was chipped both on the day it was chipped....

Would be interesting to see how you find it.

I did mine around 2 years, was told I would get an extra 100km per tank as well. (this was the clincher in doing it)
Approx 10-15kw increase I recall the quote, it was also $600.

you can tell the difference when driving in mid rev range.
But no improvement with km/tank

It actaully went backwards by approx 1%.

Keen to see your results!

Well the extra km per tank is the main reason I'm doing it aswell!! The extra power was just the Icing on the cake...
Was this the Davis chip you got??
I spose even if I don't get the extra km per tank the little more power will be helpful going up the mountains and towing the boat around

From the MY date am assuming your is a Thor upgrade engine with Bosch motronic engine management? If so, good luck with it... I'm surprised they have a chip unless it's a "piggy back" type since for all intents and purposes the motronic system as fitted to the 4.0 and 4.6 V8s from 1999 -2002 is virtually tweak proof...deliberately designed that way by BMW engineers...

I see Davis Performance offers a flash retune for 2002-2004 V8 Discos but nothing for 1999 -2001 ...

Is yours a GEMS motor?

All V8 D2s are Thor.

Yes it's the Thor motor and its dead stock not any type of upgrade what so ever, I also can't find anything on his site about it but when I rang him and spoke to Bruce he said its a chip and it takes 1-1.5 hours to install and I was very clear that it was a 00 build date and it was a Thor motor....

This is about what I would expect from a $600 chip.
Has anyone actually done better?

Well I know the old cocky got a 25kw increase and 80-130km extra per tank
