Like it says on the tin, how much is the standard set up making, and increase from K+N and full racing system?

I was told that the early injected engines weren't significantly more powerful than the last of the carbed engines, making them ~135bhp at the crank.

Don't know how they react to the mods, but it would likely need a Powercommander to make the most of it.
