[QUOTE=VehiGAZ;149667]Certainly not - I think the concern on the other forum is about whether the mods add 20 HP or 55 HP. They seemed to be looking for proof, but no one has posted anything since, so maybe no one really cares.

I just want to be able to back up the S/C power gain claim with a little empirical evidence, QUOTE]

The little brochure I have from Alpine claims a 50 hp gain with no other mods, if that's of any help.
The dyno charts are too small to really get a good look at though...

And yes, my bifocal perscription is current...
