Holden Colorado
The Colorado's are already pretty good in terms of power and economy so Mark wasn't expecting too much of a change.
Driving to work and back from Ngatea was a 125 km round trip so saving on diesel costs was his main motivation and his second motivation was being able to tow the bike trailer easier.
After we remapped it for increased power and bypassed the EGS he noticed the throttle response was immediately better but by keeping his cruising speed the same as normal he was able to notice a measurable difference in fuel consumption.
Mark was well happy ...he just forgot to notify his face when we took his pic. Typical farmer :-)
