What's wrong with an OTS map? Would I see power losses that big if so??
Not installing the turbos is quite the accusation. I might think the same tho, I guess. I did show up to the shop during the last bit of the installation so I definitely saw the turbos installed, and the old ones on the ground. Also, they were smoking before, but no smoke after! But I agree with you that something isn't right. I'm still digging for an answer.
The OTS map is built for the stock turbo. No wonder you're getting low numbers, you need a custom tune...
