Hell no, dont do that. Open up your TB some with the set screw and do a IAC relearn. Your cam is really small, no need to do any TB drilling.

Do some searches on IAC relearn

I agree, with a cam that size you shouldn't need a hole. There comes a point when I personally believe it's necessary but not for that 220 pattern cam in a 5.3L.

Biggest tip I can offer, beyond what Ben Charles said about opening up the TB a little and doing the IAC/TPS relearn...is get a Torx 15 bit and flip the throttle blade set screw upside down. This may require taking the throttle body off.

TH400, 3000 stall, 224 cam, 3.40 gears and 35" tires?

You're hurting yourself on the lack of gearing btw.

Yea, let us know when you find that set screw on that electronic throttle and have done that IAC relearn.

Some of you guys need to step back from the keyboard.

Missed that part entirely.

[RACINGVORTEC5.3]

Well there wasnt any way of getting inside the throttle body just worked on my tune harder and searched the tune repository for answers and all is good now

Seems to be a pattern as of late, no?

I think some people just like preaching what they read sometimes without even reading the entire thread.....
