I have a Santa Fe diesel 2006 2ltr.
In an effort to get more mpg i have bought a chip whicg fits onto the Common rail pressure controller. Is it under the plastic shield on top of the engine( which means removing the inter-cooler) or is the the Bosch switch/connector on the air pipe to the right as you look at the car from the front??
I'd appreciate any help with this question, thanks.
