Dyno tune brings you to peak HP in ideal situations and not driving situations like you would if your at the track or on the street IMO

when i had my Nelson tune we went out and did my tune and it was damn near instant how noticeable the truck felt....

same thing when i had to switch tuners up here in DFW, went out and found some seldom used roads and tested it out in a driving enviroment
