I'd like to know opinions on hot tunes. How bad are they for the engine even if they are low cyl pressure and low timing?
Thanks in advance.

LBZ: How safe are hot stock turbo tunes?

try to stay under 1200*. above that for very short periods are ok. I saw just above 2000* at the end of the 1/4 with a stock charger.
I never had a problem with mine and i made over 200 passes with the stock charger but every truck is different. 
Yeah,
I don't dog it all the time or anything but anytime there is a challenge, I'm not backing down. I was just kinda wondering how bad it was on the engine over time. I'll prolly get twins when I can afford them.... Prolly gonna be another year...

I'm more worried about the pistons cracking then anything. Odd that we don't seem to hear about that on the LBZ as much any more. Maybe it was just bad QC or maybe I just ignore the threads.
every truck is different some last some won't if you're worried about it stay small, stock is as close to "sure to last" as you're gonna get
when I had banks, somdedays it would spike 1400 when racing(usually ran 1300 maxed).. Since I went efi, Ive only ran 2 tunes-Mcrats and Danno. Both max 1250-1300... My truck besides small mods n sig, its basically stock, so dont know if that makes the difference on egts. Maybe if I had more fuel it would run hotter? I hold 23-24k on fuel pressure... Dont know anything about the timing on either, except the tunes dont smoke and are working for me Id save the money and wait til you find someone you trust...

Most likely not too hot of a tune. I see 1300*+ in a 0-60 run. I need twins.
My hot tune, I tow with a lot, and every hill I need to knock it down to 5th gear. THe LBZ is "rated" at 1375* by GM. Do what you will with those numbers though.
Running PPE tuners will see 2k and an Edge with attitude level 5 will see 1375*. Amount of time running at high temps is what is most detrimental to the engine. There are several guys that can provide good safe tuning and performance at the same time.
31,000 miles and 100+ passes over 500hp with no issues here. Never seen EGTs over 1600º at the trap.

I dont know where you ran at but every diesel event your truck would sit in the parking lot..
Most of it has to do with who tunes your truck and just how "hot" a tune you are willing to risk. Get greedy and you will pay.
If you tune a stock Dmax for high power, the life expectancy will go down. No ifs, ands or buts about it.

Wait a minute, you guys monitor your egts?
Sure you do, they tell you when to leave the line with the sled. Then you ignore it.:rofl:

Sometimes I'll look at the gauge at the top of the track and say, "Wow, I hope thats ok."
