    FMEM and comb stability

    Is it OK to leave a tune that bumps comb stab limit or turbo fmem, but boost is where you want, its steady all the way through and no MILs get set? I crept up with driver demand and limits and this is the first tune where driver demand said anything other than no limit. 2.0L Ecoboost, 21-22psi boost fairly steady

    You're better off setting your limits where you want them (or raising them out of the question), and then dialing in your Driver Demand to hit where you want it. That's going to be better than skating off the limiters and getting throttle closures.
