Hi Gerk,
Have I noticed the increase in power - YES !!! It basically lifts the power right across the rev range, not peaky or anything. But the best bit is that you now have you old maximum torque of 354Nm at ~1250rpm. And new max torque of 420Nm is at 2000rpm. Basically it takes away the lack of low end torque.
On the freeway grind in the morning, I use 3rd gear down to 900rpm wheras before it would not pull that low easily. Makes for a lot less gear changes.
The other noticeable difference was that before in low range, I could not back my van up my drive without stalling or using the accelorator (or slipping the clutch). Now it simple idles up in low range when backing my van in. Worth it just on clutch life here.
As for fuel economy, it is the same or better. I average 11.7 l/100kms on the freeway grind to work and 15.7 l/100kms when towing my 1.6T offroad van at 100 km/hr. The very odd occasion of country cruising without the van would result in ~10.5 l/100kms. I suppose if you did not use the power you would get better fuel economy than before, but it definetly doesn't use more fuel while driving normally.
And I don't have a problem with throttle surge in low range. Its still sensitive, but very easily controlled in comparison. Also, I think why your switch didn't work is that their is a cutout on the idle up when in gear and the clutch is out. Try it with the idle up switch and you will see what I mean. i also think its tied into the engine temp as after a while it simply doesn't work.
Cheers
Captain
