I forget the exact date but you had a raffle and I won a "Traditional Tune" from you for my 2005 Tahoe Z71 stock 5.3. Just yesterday I did a new alternator and while I had it apart, I chose to pull the throttle body and do the bore cleaning on both sides. For removal, had to disconnect the 2 small coolant lines at the bottom front of throttle body and as has been discussed in my Under Construction Build Thread, why is there coolant traveling thru the bottom of the throttle body. Turns out it is to prevent water crystal freeze up at the throttle plate, in cold humid climates.

Here in Eugene, Oregon, that is not a worry. I have seen a couple videos and read some info that in climates where the freezing is not a concern, the hot coolant traveling thru the throttle body will rob horsepower from the engine.

So, I ask you, is that claim true and if I did the bypass and removed the hot coolant from the throttle body, would that affect the "Traditional Tune" that you did to my 2005 Tahoe 5.3 engine?

I value your insight and am eager to hear your thoughts on this. If it is a good idea, for better horsepower and any other reasons, can you recommend a kit that is best for this bypass? Or just any barbed tube and butt the hoses together and a couple of line clamps and call it good?
