Good call. I believe it's the same engine with an upgrade package.
Edit: Just looked on the CO site. They have the "GE90-90B engines, rated at 90,000 pounds thrust each." I think what we were both thinking of is this, found on the GE web site, as I remember a release a while back from CO about it:
"...customers have the option to upgrade their original GE90 engines with the GE's Performance Improvement Package (PIP). The PIP provides customers with a 1.6 percent fuel burn advantage and an approximately 20 degrees Celsius increase in exhaust gas temperature margin allowing better levels of performance and a reduction in operating costs."
Unless we have of both. If so, CO doesn't have the current info on their site.
