How have you determined that proper tuning will create stress on drivetrain componants?

Indeed.
AnotherNewOwner, some research would have led you to some corollary facts:
Proper custom tuning reduces stress on the transmission by producing less slippage during shifts, which translates to less heat produced, which in turn helps preserve the integrity of the fluid, clutches, etc.
Proper custom tuning, when tuned for a higher octane point, can reduce the load on the engine at a given throttle position, alters the BSFC, and hence has the potential to lower the stress on the engine. Being as intelligent as you are, I'll leave the concept, and implications of, BSFC for you to assimilate.
"In the USA, the fuel flow for BSFC calculations is normally expressed in pounds per hour (lb/hr) while the output units, of course, are in horsepower (Hp). So, our standard formula for BSFC becomes: lb/Hp-hr . For an engine producing 200 horsepower, while guzzling 100 pounds of gasoline per hour, the equation would yield 100/200 = 0.50 BSFC. Unlike AFR (Air/Fuel ratio) readings which only reveal the mixture, BSFC data represents the power provided per fuel unit. AFR and BSFC are not equivalent."
Wittom is correct. I could have a bone-stock truck, change fluids & consumables (filters, etc) - with full documentation, as often as I changed my underwear, and then go wail on that truck on a daily basis . If I then had a warranty claim, the dealer would be hard-pressed to determine it was from abuse. Truck is immaculate, with exemplary maintenance, driver is clean-cut, wears glasses and is pocket-protector equipped....
