X is a great motor, I love driving them. Our new R offering pushes it a little further. We owe these other guys for all the research over the years, but want to optimize it for everyone.

I guess I should disclose that the air filter made 20rwhp less, so 460ish rwhp with the air filter on. I will probably race without the air filter, but it isn't a huge difference. I think that your advertised numbers are very fair to the buyer.

Injection Connection said that it should be around 550 hp at the flywheel, and I believe Jay was "advertising" the engine as 530+. It went in to the shop making 15rwhp less than the final numbers (35rwhp less if you count the air filter). So assuming somewhere between 12 and 15% drivetrain loss through the TKO600, the numbers are pretty close.
There are a couple of good places around here, but I trusted them to not scratch up the car while it was in there. And they didn't keep the car for weeks.
