Will start off by the mods I use. Mods VRSF Downpipe (Version 2) VRSF 7.5" Race Intercooler VRSF Dualcone Intakes Cobb Charge Pipe All vacuum lines replaced a month ago MHD Stage 2+ V10 98 Octane xHP Stage 3 (Line bump enabled) (All mods are used to fix the issue but none have so far) The car seems to struggle to get to redline and feels like the engine shakes a lot as it's climbing the rev range and you don't feel much torque in your chest doesn't feel like its accelerating fast as well..
