I must have a sensitive butt dyno LoL. When I installed the Eventuri I noticed a difference, not huge but it was noticeable. I upgraded the to the Bespoke filter and believe it not it did make a slight improvement. The sound and engine bling were added bonuses. I do believe the car adapts to the added air volume/flow over time so the benefits you first feel are not as noticeable down the road.
