yeah, take it to an actual tuner. Don't drill that throttle blade, there's no going back. I am completely against mail order tunes. The idle has to be tuned manually.

Agreed, A Mail Tune On A Cam Like That Is Crap, I Had Over 12 Hours Of Tuning On My T-rex Before It Starts , Idles, And Low Rpm Drives Fine.

Yeah do not drill a hole. Before you read this, know that your TPS sensor should read 0% at idle.

Try adjusting the screw for the throttle blade. Open it up a little. The only way to know for sure that your TPS value is still at 0% is to use a Tech2 or a tuning program and monitor it at idle. Here is a quick way to reset it so you don't need a tuning program.

Once you get it to start up without using the gas pedal, turn the key off and unplug your TPS sensor to make sure it resets and becomes your new position for 0% throttle.
