Hi all, I've recently heard about the ficm rollback procedure offered by PHP. I work on these trucks for a living, and I'm aware of the older trucks running better. They seem to have better throttle response at pre-spooled speeds. So I'm assuming this is a tuning issue since so many people do this rollback. My question is this: I'm running an H&S mini maxx currently, and I love its features and power (once it finally spools), so I don't really want to lose that. If I pay for a ficm rollback and then put my H&S tuning back in, am I just flushing money? Will it just go right back to whatever calibration H&S used to make their tunes?

Thanks for any help, and sorry if its a repost. I tried to search for anything related to H&S and nothing came up
