I am running 285 70/17 BFG Ko2's (probably the biggest tires you can possibly run without a lift??!)
The only other mod is the Van Compass stage 4 kit: New shocks all around, rear leaf spring helper kit (levels the rear end back to stock height) and sumo spring helper bumpers up front.
I was just into the dealer and had them check the front collision warning system (not working) and also I've been struggling with the dreaded "turbo lag" or hesitation off the line when rolling to almost a stop and accelerating again - sometimes a HUGE lag, so bad it has been scary at times pulling into traffic. I even tried the Pedal Box with very little improvement.
My speedo is about 9% off at 70 mph (at 70 mph my GPS says 75)
The dealer is blaming both issues on the "inability of the computer to tell the real speed of the vehicle". I mean really? At almost a stop the real vs sensed speed would be off by like maybe 1/4 mph??!
One of my requests was to see if they could correct the speedo for my tire size, they said there is no way to correct for a different tire size?
Is this all correct?... or is my dealer just not knowledgeable enough?
