I thought I would relay this to whomever is interested....I recently installed a coil spring and shock conversion on my 06. It has the V6 and this was the one thing that Atlantic British thought could be a problem when they developed the electronic module that essentially replaces the original air suspension module by creating a workaround. They developed it for the V8 models and thought that it might not work as designed for a V6. Before I bought the kit I called and talked to Doug who is their main tech advisor and he thought it should work since the air suspension on both the V6 and V8 are the same. So, I was patiently waiting for a sale or at least free shipping deal and got lucky. I received a 20% discount and free shipping coupon by email and went ahead and pulled the trigger. The install went very well and now with about 500 miles since the install I can say that the ride and handling are just as good as the air. Also, since I hard-wired in the module instead of just plugging it in the obd port, there are no warning lights on the dash. The instructions were good and the $800 I spent will insure no more air suspension bullshit that occurs as these trucks age. Hope this helps someone.
