Who's to say you didn't command crazy timings, stupid lean lambdas that destroyed your engine, then flashed the stock tune back as if nothing had happened? If the car is tuned, you accepted that you pay to play.
In almost every case, this means if the engine throws a fit, there is no way to prove that it wasn't your tune, even if you know it, the burden of proof is on you, because you are no longer using the same product the manufacturer provided their warranty for. The Magnuson-Moss Act does not apply here. We're all rolling the dice with our tuned cars, if anything fails, it's on us to pay.

This is correct, but pretty much everyone I talked to about what happened with my engine all said the same thing.
60rwhp from mods and a tune does not blow 2 rods 2 pistons and crack a crank shaft.
The rods and pistons are more likley, but a cracked crankshaft is nearly unheard of at that power level. Look at your car... Did you replace the crankshaft with after market to run 700rwhp? I'm willing to be you did not? Now I cracked the crank shaft at about 460-470 rwhp, which is a far cry from what your car does. I just haven't had the best of luck with mods, and I've been paying for it ever since. Even now, my car ran great for 6 months after the rebuild, now it runs like shit above 3000 rpm and no one can tell me why. I've already blown over $1000 in diagnostic charges to try to find out why and yet still no answer. Maybe it is pure coincidence, but all of this started when I went with a roto-fab CAI to try to lower my IAT temps a bit. Car ran fine up to May 8th of 2024 and I've been trying to fix the problem since.
But ya, pay to play or don't play.
Sorry OP just frustrated with my situation.
