Can anyone point me to the message that has the description and pictures on where to drill this hole in the tank?

Twice my truck has had the issue and the one time it held a CEL the dealer just relaxed the plug coil on number 6 plug.

Thanks in advance for your help

Thanks once it warms up I'll drill the hole
Since I purchased a pin drill set just for this task on Amazon

You can get this done around a minute. To make things easier, loosen up the air dam.

I haven't drilled because I have not had the issue and more so because of the comments about the water droplets building on the fins. The hole would do no good if that is the case.

I am interested in knowing whether anyone that has an aggressive tune has had the condensation shudder. With a tune that build fairly significant boost more regulalry, I wonder if the CAC would be cleaned out enough before building excessive water. Of course, engines are not supposed to run on gas, air and water, too...

On my 12 I had SSI tune and it still would have the issue happen, until I drilled the hole and never happened again, may be a coincidence, maybe I understand what Geno has said and it makes sense but I had goody I with mine. I was always in the boost in my 12, beat the living crap out of that truck.
