I have read nothing but good things about the Stiegmeier work, so I'll probably send the blower off to them this spring once it gets to be motorcycle weather again. The Stage IV upgrade looks like what I'll go for. 50hp for $545 sounds like a deal.
I have another question--based on the mods listed, does 463hp seem likely? I ask because I checked his feedback and he's recently sold some 60lb injectors, a KB boost-a-spark and an Accufab throttle body. Now I haven't asked him about this because I just noticed it and it's almost midnight, but I want to make sure that the 463hp figure is with the car as-is, not with some performance parts which have been removed. I'm not super worried about it as the guy seems honest enough, but I figured I'd ask here too.
Thanks guys!
