personally don't give 2 ***** bout dyno numbers, what the car makes on paper and what it runs at the track are 2 different things. perfect example I did a cam swap last month from a ls7 to a tick custom turbo ground and picked up 2 hp and 5 tq at the tires on paper, but at the track, picked up 4.5 tenths and 7 mph at the same boost levels. id say that's more than 2 hp

thanks for you guys input.. I really didn't know what the specs on the turbo where but dang I didn't realize the ex turbine was only a 65 and with an .81 ex housing... that's some tight stuff on the back side. Im glad if found that part out reason enough for me to want to make a change..
