technical work..code of ethics..who is responsible for what
There are so many variables involved that its hard to say for sure if the engine will or will not produce the estimated output. Even if the combination i.e. heads, cam etc has proven to produce above and beyond the output stated.
Every car is different and will respond differently to the same modifications.
Should they be held accountable? Thats hard to say. How do they know if there isn't something wrong with your car to begin with?
Its very debatable.
...so how much difference are we talking about...?
...i suppose it would be easier to negoitate if the stated claims were in writting....most shops will not do this, however....
1. Promise a bunch
2. Deliever what you can
3. Charge through the nose
4. Blame everyone else if something goes wrong!
???????????????????????????????????
Sorry guys, I could not resist after the public bashing accountants received over Enron...
You could take 10 LS1s with all the same parts, and give them to 10 different people, then dyno all 10 of them on 10 different dynos and come up with 10 different numbers. Thats just the way it is, and its also the biggest reason why the dyno is not the be all/end all gauge for performance.
I'm just a customer, but I assume anything other than fraud like slipping in a different cam or full priced used parts or negligence like mistorqueing/bad install is on me.
Who did the tuning? A vortex adds way too much weirdness for any estimates of gains. Could be it's other than the cam...maxed injectors, who knows.

If you have a gentlemen's agreement, it should be honored or work towards a solution agreeable to each. Its called customer service...
If they broke something as result of their work or caused a failed part due to stress or heat, I think they should try and support you for the mony you have to pay to get it fixed, example, promised high numbers, but may have abused a part to get that high number, on the way home it breaks or doesn't drive the same, I think they should support you to determine the cause and possibly be liable for the damages. Its called customer service.

Were the before and after dyno's done on the same machine with aproximately the same conditions?
Are you a full bolt-on car? Most cam swaps would not perform to their max if the car has intake or exhasut restrictions...do you have LT headers, LS6 intake, etc?
A peak 10Hp gain does not seem too high; but peak HP is not as important as the HP under the curve....maybe this is much improved????
How does the car feel?
Their is a reason you chose this shop for your install, let's assume it's because either you, or a friend had a good experience with them in the past. That being said, if they are a good shop, they should be willing to work with you to correct the problem. If they shine you on and tell you "sorry bub" tell them you'll pursue it legally. Gather whatever documentation you have, and I'm sure you have no promise of power gain in writing, contact an attorney and seek advice on the matter. We're wrenchers, not lawyers, and whereas there is no harm in seeking our opinions on this, this is *completely* between you, the shop, and council.
Relying on one establishment to give you the entire picture without doing your own footwork first can lead to disappointment.
The order of the day should be "caveat emptor"(let the buyer beware)!

Have they determined the tranny isn't slipping? A few times cars didn't make the power because the clutch wasn't up to it.
