fuel efficiency after computer mod
 

As JCL recommended, and i think many people are also in the same boat as i'm, really looking forward to some pros for the computer mod

i have searched (Sylvan Lake V35 helped greatly) and have not found definite answer toward a question that I've been on my mind.


IN YOUR PRESENT EXPERIENCE, DOES THE COMPUTER MOD REALLY HELP THE FUEL EFFICIENCY????

many of you owns multiple cars in the garage, and has many years of driving under your belt, and understood it all about your right foot doing the efficiency, however, like to get some consensus, in the real work, tank to tank, does this mod offer efficiency on the X5d?

What's the computer mod? I'm curious. Also, why are you screaming at me?

hi Jeremy...

the computer mod i was referring to was the JB+ (for the diesel JBD)

I don't know you...sorry didn't realized you take my bold typing as screaming...:wow:

You will use more of the available power, hence fuel mileage will drop.

Theoretically, you should be able to save fuel, if you just baby the accelerator and dont drive any faster - nor accelerate harder- than pre-JBD.

But then why buy it?

Ard! thanks for your input! I got that...:iagree:

did you get a chance to install them? like to get your take and vote up...if you have...
