[BiturboS4] New S4 owner

[Al Adler]

I'm not really sure since I'm still running V3. Since I only got my S4 a
few months ago they've had the same claim of the 307 hp @ 91 and 318 hp
@ 93 octane on their site. I think the V5 software was released since
then so if it made more power I'm sure they'd update their claims. From
what I've seen from other vendors thats about all that the K03's will
reliably put out anyway regardless of whos' chip it is.  My guess is
they're just working on the overall smoothness and the CEL problems that
some seem to have. I guess I'm going to try the V5 upgrade and see how
it affects my CEL and the feel of the chip overall. There is definitely
room for improvement in both areas on my car. If that doesn't work I
think I may be off to GIAC land...
