This patch converts the Evo X's factory 'Load' style boost control to direct psi-based boost control, making boost control and load independent factors when tuning. This enables superior boost and load control.
Free if your ROM is supported. If your ROM ID isn't supported yet, a conversion fee may apply — we'll confirm before any work starts.
