It looks like from what I have looked into that to use HPTuners to set the actuators is going to cost me 700.00 after buying the dongle and it looks like you need 6 credits to get into the exhaust settings, and I was told a dealer can do it for less than half that price, I’m not interested it making it have more power or anything like that, I just want my actuators to work like they should and from what I can tell I only have two settings open all the time or closed all the time I can’t hear them change while driving.

Just reading through this thread all i can say is be careful going to the dealer to get returned to stock tune. I may be wrong but this seems like a "brand new to you" car, and it also seem like you don't know what has been done to this car. This car may have been tuned for some part or parts that were put on that you don't know about and you could be making things bad if that's the case. I would suggest trying to find out some information about if anything is done to the car before you just go have the tune changed. If there's anyway you can contact the original owner would be your best bet to see why it was tuned out. Only because I don't know to many people that would waste money on a tune just to shut off the valves, you don't even want to spend that much to get your valves working.

The CCM is 2 credits, but I don't recall if you have to license the ECU first. Makes sense if you do. I've never only tried to change the CCM for any clients. It's always an add on for custom exhaust work.

Been a while since i was here, but I went and talked to the dealer where I bought the car and they refused to check the valves, they said it was a modification not approved by GM, I said I'll pay you to check it, NOPE it`s an unauthorized modification and you can come back on us if it causes damage to your car. I said it`s exhaust that GM puts on their own cars for customers, NOPE not touching it, I said but you did before I bought it with the aftermarket
system that was put on it when you sold it to me.

I asked if i could have the info to talk to the original owner, and I was told that wasn`t legal in Kentucky, they can not give you the info of the previous owner, only the Carfax report. but I`m beginning to think it`s not been tuned from talking with other owners of camaro and corvettes.

Do you see any sign of hardware changes under the hood or the car (CAI, intake manifold, headers, flex fuel kit, strange non-stock wiring, cat delete etc.)? If yes, it's likely that your tune accomodates those and returning to a stock tune would be ill-advised, which may well be why the dealer is balking.

I'm assuming you have a V8, by the way, your signature only says Chevrolet Camaro, not even whether it's an M6 or an A8.

Either way, I would personally bite the bullet with HP Tuners, because it'll allow you to customize everything to your needs now and later. There is a wealth of tuning knowledge even here in the forums, professionals like Megahurtz and experts such as KingLT1 or Joshinator and others who are graciously willing to help with your tuning issues, if any.

Not only will you be able to customize the NPP (we're talking setting individual RPM ranges for each mode to open/close the valves), but you can improve performance and longevity yourself in many ways, from disabling AFM (if you have an auto) to adjusting timings to even little perks like tuning the downshift crackles and pops in the exhaust.

Also, you can at least read and compare your current tune to stock using just an MPVI device even without buying any credits, that way you'll know what changes were made to the ECM and FSCM (exhaust) tune. The HP Tuners website has a bunch of stock tunes in their "tune repository" section that you can download, choose one that is closest to your specs. The transmission tune can't be read unfortunately if you have an A8, only written for some screwed up reason GM "engineered" into the system, but the other two modules are readable.
