no i don't think anyone has done a clear cut pre vs. post OTS MHD dyno yet
MHD Tuning shared a dyno from a customer with a OTS stage 2 map:

csu87 has provided some nice comparisons using a virtual dyno, his baseline reading was 271whp and saw 319whp for stage 1:

a true before and after dyno comparison would be awesome. i've actually never done it myself, a quick google search shows local shop charging $60/half hour for a 2wd dyno - is that reasonable?
either way for me i'd have to wait for more parts and cooler weather, don't think any testing in 110*F would be ideal
