Which coolant/How much?

Which coolant/what percentage?

I am gonna put in a 180 Thermostat to compliment my Hypertech tune.
I am also adding some redline water wetter to add to it.
I was wondering 2 things:

1. What is the best coolant to use?
2. What percent coolant/distilled water is best?

Thanks!

i use Prestone green mixed 50/50 with tap water.

Tap Water???
I used to always put 50/50.
But I am hearing that 25% coolant/75% distilled water is best.

Is this true?
Or should I stick with the 50/50 rule?

well we used tap water at the dealer. i just use 50/50 cause its easy to dump 2 gallons of water and 2 gallons of coolant into the flusher. tap water is perfectly alright to use. we had a prestone guy at our school and he said that it was alright to use, i even asked him specifically about the 4.6 and he said to only use distilled with orange or long life coolant.
