Bought my old evo back and Finally got my forward face turbo kit installed and having some issues with teying to hold an idle without needing to feather the throttle

- Old tune was downloaded but have the same parts as before “minus a bigger turbo and stock throttle body from having the s90”

- no IAT sensor but tuner said he did not need one and the car ran great before I sold it a few years back

only 2 things I can think of as of right now. Car ran fine before the install.
