Maybe we can get this thread back on track to the actual question...
slider3w I'm running into the same. Did extensive mods to my 2008 110" (heads, roller rockers, 10.7 static compression 9.6 corrected compression) including a complete lower rebuild and I'm hitting 108 tq/112hp. I too expected low-mid 120's for numbers. Unfortuantely that'll have to wait till spring to complete the break in and final tuning.
I'm sorry, but some of the proceeding discussion is, as stated, just plain foolish. At the risk of reading another 20 posts about how someones cousin's, dad's, grandma's dyno read different than Johnny's dyno... I'll say it anyway. Dynos are a tuning tool. For the most part if they're running the same software, set up correctly, and using the appropiate inputs they'll be withing points of one another. With that being said the biggest factor, in my opinion the single most important factor, to different dyno runs/tunes is that a QUALIFIED AND SKILLED OPERATOR IS REQUIRED.
I don't and will not argue with the ones that feel dyno runs mean nothing. When people don't understand nor know how to use the data from the dyno then they're right, it's usless to them. Years ago the earth was thought to be flat too. Knowledge is power. Knowledge helps you make engine power.
What you're shooting for is to produce a maximum torque value and carry it out through the RPM range as long as possible. You're HP is nothing more than a calculation from your dyno measured torque. It would be nice to see the dyno chart from your run including air/fuel ratio. There are many highly skilled, I'd even say experts, on here that can help to dianose engine problems utilizing the dyno data. While I'm not saying your tuner isn't skilled and/or an expert, most competent tuners would have been able to troubleshoot exhaust restrictions or maybe throttlebody/injector issues.
