I'd love to, but there's no point in it now. All it would do is see how much power 26psi of boost can make. I have no power chips, boost foolers, or anything like that right now, so the M4s are pretty stuffed up.
I'm still debating where to go next, in terms of electronics. I've sworn off my EZ (and perhaps EDGE, too). The MAD ECM was awesome, but not as smooth as I would have hoped-- a little too quirky. That leaves the Van Aaken for non-wire tappers. Then there's the TST. I like the idea of the VA/TST stack, right now. I'm debating which to get first. It's hard to justify spending $950 on a stack that will just give what a $600 Comp does. I may just end up with a Comp and call it OK.
All the 4s have done for me now (aside from less smoke and better mpg) is make me VERY curious as to what untapped potential (pun intended) lies within them. The MAD ECM really whet my appetite!
EDIT: It's also probably not a good idea to dyno such an overfueled truck with a dead Pyro!
