Nice catch. Did you happen to call them out? I've seen the inside of those intakes in person. The welds are absolutely horrid. The outside looks OK, but inside, nothing but slag. Not sure how you even do that tig welding.

Looks like you are having valve control issues after 6,000rpm that should not dive that fast, definitely something wrong, get that sorted and it with make a lot more power with both intakes fwiw
