which aftermarket ic boots would you people recommend? i have a 17% pulley fyi...it seems like the clamps bottom out before they are tight enough...causing some boost leaks....i only have 12 psi max with the alta 17% pulley
cheers

 

the stock mini ones.

 

The clamps on mine have the same issue. I even purchased two new couplers/bellows for each side, and to me they dont seem meaty enough for the clamps to get any grab. I compared them with the original set removed long ago, and these new OEM ones do appear and feel like they are thinner.

Here is a thread recently started to solve this very issue. Although I have not tried it, I have new couplers from Alta on their way, so when they do arrive I will be taking out my file and dremel tool.
