yep, had a tunit chip in my old prado with 1kz-te engine, got Berima diesel to fit it.
Made a moderate difference in power but sucked more juice.
The one you are looking at is later model , probably better now and doesn't just dump more fuel in accross the board.
If I got another one I'd get one with a switch on the dash so you can turn it on & off

I dont think Berima diesel do the tunit any more as they have another one supposed to be better.
Make sure you get one that fits after the CPU and not before it .
Safari is the best but expensive. There is not much inside these for the price only a small circuit board size of a match box.
Only thing that gives a diesel more power is more fuel and cooler air and can make them run hotter.
My van actually goes alot better than the old Prado that was chiped up and had an intercooler. Maybe Japan CPU is already beefed up a little bit.My mates Japan import Prado went heaps better than mine thats why I got it chiped in the first place and still was not as good as his.
Lot of homework to do on these things , let me know what happens
Cheers

Thanks for that. something for the future I think. not desperate for more pwoer but like blowing the BMW's away up the Wollongong Hill!!

aw dont pick on the beemers !

Fair game?

Aren;t these just glorified resistors.... ?

i know a lot of these so called power enhancers just foold the engine into thinking that the air is cooler or the air mass is greater, allowing more fuel in.... yep, gives a bit of power but doesn't much help the motor in the long run.... and if uou know what you're doing these resistors can be picked up for an electrical outlet for peanuts ..
