i really don't think weight savings off of your UIM will actually enhance your performance. . .the SVT UIM isn't that heavy for an all aluminium UIM anyways, and most importantly, for people like Demon and myself who've EH'ed the crap out of it, there isn't much left in there!!!
I wish I would've measured pre and post dyno measurements of the extra EHing on my UIM, but alas, one could only surmise that the extra smooth lining inside (which THAT design CERTAINLY doesn't have) can only enhance the flow. . . .
