- Do I need a custom tune?
- Although the Megazilla can run with a standard ECU setup, a custom ECM calibration ensures optimal air-fuel ratios and ignition timing.
- Is VCT fully deleted on this engine?
- Yes, the high-performance camshaft features a VCT delete for a simplified valvetrain and improved reliability at higher RPM.
- Can I use stock exhaust manifolds?
- While some OEM manifolds may fit, long-tube headers or upgraded manifolds generally offer better flow for maximum power.
