dbaker,

Did you find that the BMS filter had any significant or noticeable performance gains? ...or any improved responsiveness or improved drivability quality?

Please describe your BMS air filter experience on your LT1.

Thank you!

This produced a noticeable loss of hp compared to my stock GS and my wife’s Stingray at 700 feet of elevation and 93 octane fuel. Good times for sure though!

You are absolutely correct as the elevation alone would kill 7% power and I have access to 94 fuel always so that would be the difference
