I do prefer a cable connection between the throttle pedal and TB though - not a big fan of the DBW setups in the cars I have driven. Presumably with a good tuner it shouldn't be an issue though.

The 90 mm throttle body is off a LS3/7.
The DBW set up allows cruise control, tunable throttle progression, no linkage and no idle air control motor.
With some tuning it feels good, or I’m used to it.
I also hate the feel of cables and solid mechanical linkage is problematic.
The new LT torque base engine cals do have poor throttle response. It can be calibrated to be better but not as good as the PFI cals.
