H&S 300hd tune

[drhoades3862]

I ran this tune on my truck for almost 9 months till my engine failed. Cracked a piston in half and cracked both heads. The 300hd tune runs a way to much timing. My heads and pistons are proof of it. The injector spray is almost to the out side of the piston next to the cylinder wall. Just be cautious when running the 300hd tune for H&S it just cost me about 7 grand. I love there products and wont change tuners just want every one to be aware.

what kind of operating conditions?

I've run the same tune for over a year and almost 60k miles

I was just saying...lol.

Did you just do it to be safe or have you had engine issues before?

Thanks for the heads up that abusing a tuned truck can have repercussions!

I ran on hd300 for a few weeks but its just so dang touchy and I have a feeling it will get me in trouble. I have been on no power or mild ever since

Who was that directed toward?

If to me I wasn't abusing my truck. I had actually just installed the mini and was doing a trans relearn when they blew

Ok, gotta ask!

How hard are you on it, do you sled pull or drag race it all the time it what?

I've only been running the hd300 for about 3 weeks now but when I do hammer down on her it's just to about 70 mph or so and then I back out of her.

I have done everything but studs.
