Not for the LBZ, just the LLY, LB7 Diablos did that.

They are sending me new a code blocker to try out though with my LBZ

In the meantime I bought the Edge Evolution and will compare the 2.

My mileage has gone down with no explanation except the Diablo upgrade. I can see the Turbo pressure has gone up some but I drive easy!

Still need to put the MH pan on but haven't bought any fluid yet, plus I have transgo jr kit to do at the same time!
