So far, I have almost 3000 Miles on my Pro. About 2500 is under 8-12 PSI of boost w/a BD turbo. I ran stock reeds fro the first few hundred before the turbo, and then another 500 or so after I installed the Turbo. I switched to Boyesen's "Turbo" petals for a couple hundred miles, but after a buddies failed (I installed his turbo, as well as the new petals at the same time I did mine), I checked mine, and found some chipping and cracks. I talked to another buddy who runs the RMSHA circuit for BD/Durmas Racing, and he gave me 2 extra stock petals, and told me they were doubling up the bottom set. I tried this for a while, but it seemed to me like I had picked up a bit of a bog. I talked with several other people who had tried V-Force and had got very little life from them, as well as Jared from BD. He told me that through their testing, the stock petals were performing and lasting the best. I went back to the stock set up (removed the double set on the bottom), and have been running that since. With my engine tore down currently, the original petals have a little bit of chipping, and some separation from the cage, but are not terrible given the life and use they have had. I will definitely replace, but in a pinch, would probably be ok flipping the ones that are gapped.
Also, I would like to mention, that this is the first time I have EVER had an issue with Boyesen reeds. Normally, I think they are the best on the market, but for some reason, do not like boost in this particular motor.
