H&S defuel levels

[19th_AT]

Just curious what everyone is setting their defuel levels at while running a H&S MM with HD tunes on it? The preset is 1450, also what are safe levels to be running at? Thanks

Ect 220
Boost 45
Egt 1450
Trans 190
However my defuels are disabled running kem tunes.

Whats the cold coolent sitting for?

To let your truck get to safe operating temps for the added horsepower setting. Basically a safety feature for your right foot. Not good to run her hard until warmed up. Sorta like ur body.

Wilson is right, it keeps it on the no power setting until the truck reaches your selected cold coolant level and then it ups it to whichever level you had it set on when you shut your truck off. I run mine on hot but when I first start it up it will stay on no power until the coolant reaches 160 then it adjusts up to hot.

when i do a wot run with the tq locked i can hit 44 psi with the kem 345 is that normal? also is that safe for stock bolts? just came from a 6.0 and know thats not good for them but these turbos are way different

I would imagine that continuously pushing the boost past 40 would eventually cause the stock bolts to fail. Every once in awhile wouldn't be that bad but I guess it only takes once so they could go at any moment anyways.
