Re: Best way to get the most HP out of crossfire limited!?!?!
I would not do a tune WITHOUT FIRST a CAI and Throttle upgrade, and maybe injectors - I don't believe MB "left that much off" the engine as-is.
Of course, there is the thing where this engine did 230 HP in the SLK320 and supposedly only 215 in the Crossfire; they either 'de-tuned' it OR the published numbers are not real.
