Ultimate Sea-Doo Upgrades: iDF Delete, Tunnel Reinforcement & Calas Performance Mods

We took a brand new 2026 Sea-Doo GTX Limited and completely transformed it into an 85+ MPH absolute rocket! 🚀

​In this episode, we are diving deep into a full performance build. We start by deleting the iDF and reinforcing the tunnel to handle the crazy power we're about to add. Then, we tear into the engine to install a full suite of Calas performance mods, including the Calas Cam, springs and retainers, a lightweight flywheel and magneto, and a lightweight cam gear. After dialing in the prop, we hand it over to Chris Caputo Jr. to get it perfectly tuned.

​The best part? Seeing the owner's reaction when they feel the jump from a stock 67 MPH all the way to 85+ MPH Close to 90 MPH. You don't want to miss this!

​🔧 The Build List:

​iDF Delete

​Tunnel Reinforcement

​Upgraded Prop

​Calas Cam

​Calas Springs & Retainers
