EVP ECU tuning for Sea-Doo GTR 230 models delivers muscle craft performance in a budget-friendly package that completely transforms the riding experience. More power with less OEM limitations unleashes the Rotax 1630 powerplant’s capabilities with crisp acceleration off the hit, higher rev limits and higher top speeds for a totally revamped ride without breaking the bank.

• STAGE 1 BENCH FLASH ONLY: Includes EVP GTR tuning file
• STAGE 1: Includes EVP GTR tuning file, Solas 14/19a Impeller, & 159mm Wear Ring (ECU Bench Flash via mail-in)
• STAGE 1+ (For 2020+ GTR models only): Includes EVP GTR tuning file, Solas 14/19a Impeller, 159mm Wear Ring & EVP Intake Kit (ECU Bench Flash via mail-in)

Ease your way into more power and less factory restriction with Stage 1 tuning (software only) or go big with EVP’s Stage 2 packages that include the OEM 159mm wear ring, Solas 14/19a Impeller to reduce cavitation and thus eliminate lost power, and optional EVP Cold-Air Intake (for Stage 3, coming soon). Regardless which route you take, all are guaranteed to deliver a night-and-day difference on the open water.
