^^ Hey Shaun,
Well, I was told by ESP that the center diff, or is it transfer case, needs some love, (a change of fluids) and is causing the wobblieness on the graph, so maybe do both at once? haha
But really right now it is frighteningly quick as is. Very different car now. The E85 makes it come on boost a lot quicker and ramps harder.
Feel free if you want to come visit, and i'll take you for a spin.
James
