Welcome! Some people have the change in power/acceleration after recall, others don't. Either tune the truck to override the change or sell it. Really the only options at this point.
I hope they are lining your pockets for those plugs daily. :D
In all seriousness... a person shouldn't need a tune for a factory emissions equipped truck to function properly.

Welcome to you both..
"Tuning" is re-writing the factory calibration for more power and usually better fuel economy. "Deleting" is removing federal mandated emissions that really is against the law, but some companies do offer a way to do it.
