As I understand it, the pro series have the ability to move more air quicker. The guy that tunes my car does R&D testing for holley and has worked extensively with them. In my combo (1000hp street car) he said there is no need to change from the standard holley valves I run, but in a max effort, all out combo, they 100% are a better choice.

With regards to PID settings, have you guys been able to dial them in so that the valves stop intermittently clicking when not in boost (0 psi)? My only remedy was to offset the 'Dome Pressure' sensor by 0.15 psi.

The issue that I have always wondered about is the 100psi/second maximum rate of change? .... would sure be helpful to have that number higher if these solenoids allow more flow and control? It’s not uncommon for me to exceed this limit on a good track? ...

Their sticker makes that more expensive too.
$41.29 + $129 shipping. Obviously its much larger and heavier than it appears in the picture! lol

Any back to back test results on boost control ?
Thanks
Hyperaktive 160lbs setup is clearly the best way to go 8 to 10 time faster than most if not all valves out there and tracks the desired target almost perfectly just my 2 cents 😜
