I have a 2020 STI and have installed a GS divorced, cattery DP, INvidia N1 3″ cat back. Also a Cobb stage 2, 93 tune and a turbo blanket. The next step is to upgrade the fuel system as I an seeing 96% duty cycle on the injectors.
I really like the IAG kit but it requires TGV deletes. Will TGV deletes hurt my low rpm torque and throttle response? I have observed the TGVs are closed at low throttle opening even when the engine is at normal operating temperature.
Thanks,

You don’t need TGV deletes to run any of the fuel systems, they do work with factory TGV’s you just cannot run the injector covers. TGV deletes are a great upgrade and we don’t see any downsides.
