I and waiting for the stage 2 upgrade to arrive but was just curious.
I has stage one installed for a few weeks and was not impressed at all with the gains. I ended up returning it since I thought the risk of potentially voiding the warrant does not justify the alight gain in power. I've been waiting and hoping for some other company to come up with a flash tune.
