For the price it's good quality and performs well. It's by no means all out max effort best you can buy. If I had a drag car then it would have a better core on it, but mine is a play toy street car. For that it outperforms the ebay by miles. For $500 it's a great choice. It has a small pressure drop and the iat's stay in check.

 

I have had some custom built ones, but the last 2 were the Treadstone 25's
I was pleased with them, the IAT's were good, even in the hot weather

 

Not sure how it is going to perform yet but the quality and price were excellent.

 

Its a good middle ground between the china crap and the custom high end ones.

Mine drops around 100* with 1-2 psi drop

 

From the pics i have seen I think their welding could use some work but apparently they work and don't leak. Other than that, I would buy one from the performance I have seen from them.
