In the end i didnt chip it,
I was so close to having it remmaped by a local tuner, but being a automatic, i had concerns with Torque / Kick Down and Lots of black smoke.
I just chipped one of our Renault trafic vans, and it smokes like a good one now, so didnt go through with the Navara one.
The 2.5 Engine in the Navara, in my opinion has been tweeked enough, my other concerns were the longitivity of the engine after a chip upgrade.
The Navara is very quick ( for a 4x4 ) out of the Box, i love my power, and i still havent bored of the massive mid range torque of the standard Navara Engine.
Which model have you ordered mate ?
