Jeep Wrangler 2.0T GPEC4 tuning

Hello everyone,
I'm trying to deal with the GPEC4 ECU of my Jeep Wrangler 4XE, which is not as easy as I could expect.
Looks like boost control is made only through compressor air filling maps, but honnestly I'm struggling to understand the way it works. To me it's a bit like an Ecoboost management, with throttle control for everything.
Does anyone have any experience on that ECU?
Any help would be very welcomed :)
(Also, Can't figure out a way to avoid catalyst heating procedure on warm starts.. would be interested on that too :D)
Thank you !

i dyno'd one the other day impressed compared to penstar
