Back ground, 93 4.2td patrol wagon, after market turbo, 3in mandrel exhast, snorkel.
I'm looking into having a fuel compensator fitted and from what I've managed to find out about them it looks like a good idea. I like the idea restricting fuel flow at low rpm and opening it up as the rpm increase where the engine/turbo can utilize it better. Interested in the opinions of others, pros/cons, personal experience.
Currently my fuel consumption is 13.5-14/100k's (90% city), and from I could determine shouldn't be too different after fitting.

I have a Hilux 2.8 diesel with turbo fitted. I recently had an "aneroid" fitted to improve low down fuel usage and smoke levels. It also improved top end power and general driveability. I have not noticed any negative impact on fuel economy. If anything it's slightly better.
I believe this is similar to what you are considering (though I could be totally of the mark). It works a vacuum system and as the turbo boost increases so does the fuel feed. I am certainly happy with mine. It was costly though ($1,000).

One other point:

I think the most benefit is in country driving. You don't really notice much in the city. Bit the same as having the turbo. No great benefit in town but on the open road it's a plus.

Cheers
