Unless you have a 'yota, which are the least friendly to aftermarket tuning, this can be adjusted, typically on a chassis dyno using electronics like EFILive or HPTuners. But if the change causes damage, it's your liability and expense.
Best way to circumvent the risk while still getting the results is to try different final drive gear ratios. Then it's just correcting the speedometer / odometer, and for automatics, the shift points. Not a big deal, no impact on the annual emissions test.
