was that 2 mpg on the 87 tune, or a higher tune?When my wife's '08 was bone stock, we added the Flashpaq and received a 2mpg increase in AVG fuel economy both hand calculated and displayed on the cluster.
We've done things since that have harmed the economy such as larger tires, etc.
I took that differently than you, I thought he was worried about it, not wanting to do it...From the factory, The 3.8 runs extreamly lean, why would you want to lean it out more?
