Factory set fuel delivery only enough to match 5psi of air would run so lean it would stop the engine if you were actually ramming 10psi into the mix . A bigger injector delivering more fuel than the ecu is aware of could bring the fuel air ratio back into spec .

Double numbers is a bit extreme but it helps to get the principal across .

Shayne just pointed me to this thread so I am pasting my pm question to him:-
Hi Shane, as you may remember I relatively recently bought a 197000Km J95 Prado and I am very happy with it. My KZ-TE is bog standard AFIK but the turbo boost is turned up to 19 I think???

However, it is always nice to have more power! I was just reading in a EGR blanking thread, that you fitted an inter cooler. Mine does not have one. I never had a diesel before and my head is spinning! EGR blanking/oil catch cans/intercoolers (flat v vertical) so much to learn!!

I am so screwed up just now, I am asking you this question, and walking away from the PC for a day or two just so I can chill! :grinning::grinning:

Anyway, with hindsight, do you think it is worth fitting an inter cooler?


PS I will now read the whole thread when I can find time.
