Tuning over 105kpa in HP Tuners?? How do you tune for more than 105kpa in HP Tuners?
I've hit 105kpa N/A and was wondering if I wanted to tune for a dry shot or for forded induction, how can I tune for more than 105kpa that I'd see under these circumstances?
Thanks.

For small boost a lot of people just forget about it,
because the MAF is pretty much in charge over
4000RPM anyway; they just fake it with the PE
table.
For big boost you may be past the MAF limits and
want to go speed density with a 2-bar MAP sensor
(200kPa). HPTuners wants some extra dough for
their 2-bar option (which I think is a minor hack to
the OS, they customize it for you?). That and a
2-bar MAP sensor and you're good to go.

I ran a dry shot on my v6 for a while. (a 150 shot at that...)
The maf took care of part of it, spraying through the maf will bump up the fuel, unless you max out the maf...
On the v6 I was also able to use the feature for applying a small amount of nitrous to the vacuum port on the fpr to bump the fuel pressure. If you had a vacuum referenced fpr, you could get the regulator assembly used for a v6 kit and bump up the fuel that way some too.
