Question More HP out of the new 525 EFIs

Does anyone have any info on Mercs. new 600s? Can my 04 525s be upgraded? Has anyone put whipples or anything else on the new 525s, and if so what kind of tunes problems have you faced?

A guy on our Lake put the whole kit with intercooled intake on his 525 EFI PM me if you want to talk with him.

He said this summer thay are up to about 6-8 kits installed.
