My fiscal logic on the GDE tune SOLUTION to the EGR:
$200 ebay egr valve
$200 install said egr
-------
$400 = EGR failure cost, apparently a close to 100% failure rate
450-400= 50$ to recoup in saved fuel if you think the egr might only die once.
My fuel costs and tire costs are likely going to go up actually since I accept the fact that you have to pay to play
I personally, after having tuned my jeep, doubt I will be able to recoup that much fuel in regular driving since the 3-5MPG benefit assumes you have the restraint required to lift your foot back out of the now fun skinny pedal.
Now that on damp days I can get 4 wheel drift off a left turn launch.... and still get 20MPG in the city.... Could you take your foot out of it??
