1) TTI posted their gains and has done testing for a couple months now . OV still hasn't released any progress or gain numbers.
2) TTI has excellent customer service! Tony has been super helpful and kept in touch to answer any questions that i may have. I messaged Matt at OV and didn't get much information.
We just have to wait and see what the results are.
