Hey guys.

I recently went from a jb4 to mhd stg2+ and it's been fantastic. I'm wondering what boost targets I should be hitting? Today I hit 18.9 it's middle of winter here so it's pretty dam cold and I'm running fbo with 98ron. Is this a tad high? My jb4 rarely would go over 15 or so.

Also if I'm hitting 18.9 now what would e20 be pushing?

Agreed, MHD (i'm on stg 2+ also) feels great. So with that said, yes there are boost targets but BMW uses load targets and will run the least amount of boost to reach that load (this is my understanding by the way so if i'm off, i'm sorry)... In the cold, it will be able to reach its load target with much less boost, when warm it will crank the boost up to reach its load target which sometimes results in timing corrections if octane is an issue.
