Pretty much ya, Greddy T517Z turbo, Japspeed Manifold, Z32, 460cc Injectors, GTR Fuel Pump, Alloy Rad and Intercooler, nothing internal, no cams or forged anything, engine has always pulled good and strong...
See if the Power FC is still set to having a Z32 fitted on the commander, if not then there is a chance it has lost its map.
