are tuners still recommending to drill the throttle body blade to
help with high idle issue?

i thought that was a sign of a **** poor tuner?

anyhow i believe that aint right,
my engine doesnt idle right so the tuner points fingers to anything but
his tune.

is this practice still going around?

he says he is using HP Tuners!

W T F !

It is in the tune. No need to drill.

Tuner doesn't know how to idle tune. It generally cause more idle problems..

I am running a Nelson tune and having the same damn problem. Very aggrevating pulling up to a stop and truck wanting to die. Yeah mine will be getting dyno tuned shortly.

only reason to drill is when not tuned and it will help it stay on till u go get it tuned

Idle is tougher on the DBC cars/trucks. If you have a huge engine that pulls a lot of vacuum you may need to drill it slightly, but not a ton. Basically the engine needs more air than the IAC valve can supply. On DBW TBs this is a non-issue. Notice on stock LS1s the TB is drilled...

On a side note, I bought my TB second hand, it was drilled, and my truck idles fine.

very true, i had to slightly drill mine cause the engine was pulling so much vacuum, no issues at idle neither

My dbc is drilled. It's not illegal just frowned upon.
