I am in the process of installing a 2GR FE engine in a Mercedes 190E which is to be used for Circuit racing. The engine currently is factory stock other than Headers and custom intake manifold. I plan on using the Link G4X Xtreme ecu. My question is does anyone have experience with the power difference of bypassing the VVT system , the engine will run in the range of 3500 to 7000 RPM
