It might not effect the peak but it will definitely effect how quickly you come up and the intensity of the come up. That's my experience anyway
ThisOn paper the Cmax and Tmax are not affected by food (high fat/protein meals at least). So in theory the come up and intensity shouldn't be affected, and peak plasma concentrations should be maintained longer. But like Chris said, everybody is different so YMMV.
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4307648/Exposure to hydrocodone after HC-ER 20 mg was similar in the fed and fasted states, as assessed by area under the plasma concentration versus time curve from time of dosing to time of last detectable concentration (AUC0–t; 316.14 versus 311.94 ng ? h/mL); relative bioavailability (Frel) was 101.74%. Differences (fed versus fasted) in hydrocodone mean maximum plasma concentration (Cmax; 28.86 versus 22.74 ng/mL) and median time to Cmax (tmax; 6 versus 8 hours) were not clinically significant
