Here are the results in 3rd & 4th.





Perhaps the OP's hardware is faulty? But 2 different cars with similar results, one @ 6000 miles while the other @ 5000 miles. Note that the baseline used was done a few days earlier when I tested another intake.

Just posting my findings.

Regards,

so you lost 8 peak HP with the AR intake and gained 1-2HP in the middle? to these intakes.
