Well I can say you are spot on about the tuning. 210-225whp should be easily attainable but with only 90octane gas you might be alittle limited. The xcalII won't do any actual tuning itself but you can have someone tune it for you, load it on the Xcal and then load it on your car. Just do some reasearch and look around the site. You'll find everything you need.
