Well, when I inquired about that via email, I was told this:mituc wrote:This is completely do-able with the current software. However, keep in mind that one of the ways to figure the cylinder pressure is load, because load tells you how much air gets in. Apart from telling you the mass of the air you have in a plenum with a well known volume, boost is just a measure of the resistance the engine fights back with when throwing air at it.
I suppose if your sw works like it's supposed to, and doesn't limit your load to 2, and doesn't make it run lean regardless of how much you adjust your maf sensor, then I'm sure it can be done, yes.mituc wrote:The email you've got states that it doesn't support boost target tuning. However, if you look at the boost target more like at a boost limit, there's no problem accomplishing what you want.
I know because I did it.

Dude WTF? My car IS one of them.

However these cars with a cap to load 2 are rare occurrences. Yours is not one of them. So not relevant for this discussion...
