@stuffle69 Really went digging to rehydrate a thread from 9 months ago.
The OP hasn’t signed on since 10 days after he asked the question...and the guy who originally responded hasn’t signed on since November.
Ya’ll are ridiculous.
Oh hey, every vehicles I have owned in 20+ years has been tuned. I have Never had a warranty issue because of it. Heck, my Edge Sport had the Motor replaced at 22K, and was tuned for 20K of that. The head issue it had was a known problem, so Ford replaced the Motor. No issues! Tuned it again after 500 miles.
I even owned the dreaded 6.0 Powerstroke. Had 3 oil coolers, and 4 egr coolers replaced under warranty while tuned. Had an independent shop, stud, and delete the EGR cooler, and the dealer still replaced several injectors under warranty.
Yes, it is possible, but not a guarantee! Always a risk.
