HP Tune and Vitesse Throttle Controller
I've heard about Lamb's service (I'm relatively new to the area) and it may have been that particular case; it sounds familiar. However, I talked this job over with Dave Severson, their performance shop guy, and over the course of an hour I got a pretty good idea of what they'd do and what to expect. I also talked to the tech for a while after the job. He came across as knowledgeable and straight.
I've installed, set up, and road-tuned a couple of aftermarket Harley ECMs on built motors, and while they are less complex than this job, neither am I wide open to bullshit about maps, trims, interactions, etc.
All that being said, if they got to me anywhere it was in leading me to believe that the task cannot be done at home, so to speak. I didn't figure it took a $6000 computer to do it, but I did accept that there was interaction required on line with HP. Not so? If not, then shame on me for not calling HP Tuners first.
If you're agreeable, PM me with some information on Schpenxel and the home-tuning process. I am a recovering Harley gearhead, but new to Corvettes. My friends used to accuse me of wearing out more Harleys with wrenches than with throttles.
EDIT: I just went thru the thread again and noticed at Schpenxel is a person on this forum, one who made one of the less useful comments. Is that typical?
I'm a student tuner. I started a single project that I've been working on for two months now. I am not trying to become a tuner; I'm trying to perfect one tune. I'm getting there learning the hard way, taking good/helpful (key words) advice when it comes...learning...trying...then retrying...testing what I'm being given, on and on. I've worked my single project now and I am reaching the level of satisfaction for which I was trying. I spent ten days "street tuning" to achieve what a crack tuner could do in a couple of hours on a dyno...but I'm there now and thankful to the source that got me there
This is a big site there is expertise here willing to help you and mixed with a whole lot of bull$hitters too. The challenge is to weed through the BSers to get to the genuine expertise. It's not easy. Some members here are just for the "stir" of emotion and never add any real value.
It was coincidental that I happened to have direct experience with work out of the back room at Lamb. Not atypical of most dealers' back rooms, frankly. In fact, about a million years ago, I was a tech in a Chevy dealer for two years before going back to school. I know first hand the incompetency that can be found in any average dealership. Some real talent too, don't get me wrong...just like here.

Nearly everyone who responded was reacting to the show and story they put on for you.
schpenxel and Unreal are two of the most knowledgeable and helpful members of this forum...if they say something doesn't make sense I'd listen to them.
You have become defensive and are not listening to what has been offered. But now this remains;
You have been led to believe this is a bigger deal then it is. OK that is over.
You have been charged maybe more then it is worth. OK that is over.
Now it only remains to see if you got a good product. If your tuner will send you an email copy of the tune or someone who has HP Tuner software can download your tune (can be done at no cost) and attaches it to this thread, there are several experts here who can tell you if you got your monies worth. End of story.
I call it burger king syndrome. If you never had anything but a whopper, that is going to be the best burger you have ever had. Without trying any others, its silly to claim how good a burger is.

Exactly what my opinion was after reading the OP's writeup on the Vette Sette website. It's a typical reaction when an owner who is mostly satisfied with the factory product, but later makes a change without doing research. What then happens is that other people read what the uninformed wrote and assume, in their own ignorance, that it's the best thing since sliced bread, which perpetuates the problem.My advice to the OP, is to remove his tech tip from that page.
Now as far as the "best" tuner is concerned, the best is the one who provides a tune that completely satisfies his customer. Apparently the OP has had buyer's remorse, so that wasn't the best for him.
The Best of Corvette for Corvette Enthusiasts





That may be true for you, but for Joe Blow Vette owner, your opinion of a poor tuner is still a good tuner if he satisfies the needs of his customer.You don't need a top notch vascular surgeon to stop a wound from bleeding when the fire station paramedic can accomplish the task.

But, as Jim2092 said, that was then and this is now. I feel some progress, especially with some PMs I've received.
Above, HOXXOH hits the nail on the head. I went into the process looking for a specific set of results and I got them, mostly; enough to be satisfied: some improvement in performance and a set of transmission shifts that suit me. Are there a couple of ****les? Yeah, and I really don't care enough to pursue them except sometime, out of curiosity. No buyer's remorse, at least not yet. I certainly didn't think it was the perfect tune, best since sliced bread; only that it was okay for me.
The remaining question in my mind that flows from all this furor is this: Did the dealer do me wrong in what he sold me and told me? To answer that, I've contacted HP Tuners to see what they demand of their vendors.
And once I've heard from them, I'll get the maps from Lamb and post them here.
And if they are truly fxxxed I'll edit the website to reflect it, and then get the software and begin, with help here, I hope, to work on them myself. As I said somewhere else, I never screwed anything up so bad I couldn't throw it away.

Go to the WS and download for free. That's the way I started.

I'd been assuming, without reason, that HP would be similar to Zipper's Thundermax in the Harley world, an outfit whose product has a selection of canned maps available that they developed on a dyno, selectable based on the basic engine and typical mods. T-max provides technical suggestions and support to the field as users refine their basic tunes.

Not the be all end all..but will help shorten the learning curve on tuning software packages and it's uses..
Their system works on GMs, Ford, Dodges, Mercedes and other cars. They just crack the ecu. What you do with that is all up to the end user.
They are nothing like T-max. HP tuners is like Microsoft. The ECM suite is like MS word. You don't call/email microsoft on how to write an essay. If you have a technical question on how to save a document they can assist in that just like HP can assist in how to download a file or interface. Asking them tuning questions is like email microsoft about your kids college paper and wanting help on writing a book report.

I don't know what site I looked at before I entered into the HP transaction, but I don't think it was the one I just escaped from. This one has way more information.
Thanks to all.
