Hello everyone. As the title says i rebuilded the engine and installed a custom turbo kit. Oil feed to the turbo comes from oil pressure switch. I have a sandwich plate with oem oil cooler removed! The oil pressure is 2.8 bar at idle and 6.2 stable anywhere above 3500 rpm. Vtec solenoid kicks in i can hear it clicking. I have a storm link ecu. Turbo spools up but the engine does not rev fast. It seems like vtec does not engage. I saw a few similar posts here but none has a solution. Any advice will be welcome.

 

Most time its oil pressure issue or tune related.
