Where are you located? It would help if you would complete your profile. Is your engine a diesel? You may have more assistance with your technical query on a European RAV4 forum, such as Rav 4 Club - Toyota Owners Club - Toyota Forum There are other clubs as well.
Are the diesels turbo charged. If so it could be possible to achieve 50% hp gains. It will most likely require additional items like injectors, fuel pumps, turbo, intake, exhaust, exhaust manifold, POV or wastegate. Doubt your engine will last very long with it running that kind of power.
It's turbocharged, i need all of that for that chip,i didn't understand that clearly, i need all of that if i don't have turbo charger or in both situations. I think all rav4 have turbo's.Thanks for answering.
All Diesels of at least the last 20+ years are turbocharged. Raising their power output a modest yet easily noticeable amount is done simply by reprogramming the ECM for more fuel and more boost. Going crazy to the point of breaking other drivetrain parts requires the types of mods MrPulldown lists.
