I've asked it in other threads, and nobody seems to respond...

So then, I'll ask again!

Why not just get an ECU, same make/model from pick & pull or wherever, and swap it, flash that one and preserve the original in unmolested state. Then if there's a problem, a simple swap back to stock is all that's needed. No? What other modules, record and store information? That is the question...

As for XHP... I can't see how changing shift points and maybe line pressures would void a warranty unless torque protections were disabled. Just my $.02...
