That's a 46hp defeciet that it would have to make up right? How much hp can you pick up by adjusting the fuel curve and spark? You can get a butt load. I can honestly see picking up 50-60hp with a standalone. Why? Because you lose some of the most restrictive portions of the intake and you can tune for power instead of fuel economy. 1) you lose the AFM providing less restriction on for the engines intake. 2) you can lean or richen the fuel to make the approriate AFR 3) you can retard and advance the spark to where the power is.
Is that not accurate?

Apparently the 186whp was on a conservative tune. If that makes a difference.
