too much vs enough hp

i have looked over a lot of posts regarding tuners, exhaust mods and intakes. i feel like im beating a dead horse by asking. i know how much more responsive these engines are after tuning, but how much is too much. where does a guy draw the line? at what point will the HP gains be to risky to run and comprimise the reliabilty of this engine? i paid good money, as we all have for our trucks and do want to have some fun with it. But i dont want to have pre mature engine failure. i realise that spartan and h&s are both good products and i dont wanna hear back and forth BS. i am just curious at what a guy can safely run for hp gains....

All of what you have asked will give you quick throttle response. There are forums out there including this one that will answer all of your questions in detail. In short if you drive your truck responsibly with a tuner it last a lifetime without issue. If you drive like a mad man be prepared to pay

People will destroy their engines with stock HP driving like an idiot. Also people have engines with long life and big HP numbers driving responsible.. It's up to you to make the call on when enough is enough.

I don't think there is enough data yet to clearly answer your question. By the time there is enough data you will probably have another truck. We have a truck that had a very short run, 3 years. Not enough trucks built to get and meaningful data. But i do see them around now with 250,000 miles and they are still running. My truck has been deleted for 8000 miles and it does as you said run so much better. Also, I sent an oil sample at 5000 miles and it was perfect, the best report I ever had. So I expect to get to 150 to 175 thousand miles without a majot problem. I run an edge programmer on step 1 only (+35HP). I had the same concerns you expressed so I drive it like an old man, which is easy for me becaquse I am an old man. Now, I don't think there are any free lunches, if you load up with a big HP tuner and run the truck like a drag racer or use it to pull sleds then I think you would probably have an early engine failure, but I don't have any evidence to back that up. This is probably not very helpful but in the end you are gonna just have to make your own decision and live with it. Hope this helps you decide,
