how do i find out what chip i have?
Does anyone know and easy way i can find out what chip i have in my car?
See the car had been chipped before i bought it and there arent any reciepts or anything for it so i just wanted to find out what brand chip upgrade it was.
Any help would be appreciated.

Open the ecu and look inside. 99% of the time, the chip installer will leave a sticker on the chip that identifies the maker and version of software.
If there's no sticker.... Unless it's a TAP with it's telltale minimal boost, there will be no way of knowing for sure.

I see... well they" told "me i would have 50 hp with only 12.5psi .. is this possible

Hp numbers are only a part of the picture.
What most people do not realize is that 1 bar chips on a K03 are making ~ 0.8bar at the power peak of 5-5500 rpms. The size of the turbo and octane content of pump gas limits the amount of boost produced at these higher rpms.
YET, there is a huge difference in acceleration and feel between a 0.8bar rated chip and a 1.0bar rated chip. The 0.8bar chip does not produce the *torque* that the 1.0bar chip does, and this is what people really feel. The entire area under the curves must be paid attention to. This is what shows the real differences between chips, *not peak hp ratings*. The more area under the curves, the faster the chip will feel and perform. A 1.0bar chip will produce 1.0bar *on average*. They produce a little bit more than 1.0bar during overboost (low rpm full load), but less than 1.0bar at high rpms. The same characteristics apply to the stock and 0.8bar chips out there.
Conversely, what some people do not understand is that boost rating is not the only gauge of power. Ignition advance is also a very critical component to ultimate power output. You could run 1.6bar all day, but the chip would feel and perform slower if full ignition advance was only, say, 1-2 degrees. Thus, it *is* possible for a 0.8bar chip to produce more power (hp or torque) than a 1.0bar chip if it has a significantly more aggressive ignition advance curve (until pinging trips the knock sensors).
However, each 1.0bar chip we have dynoed currently available on the market has had significantly more area under the torque curve than the 0.8bar chips we've dynoed. Apparently, the current crop of 1.0bar chips is sufficiently complex enough in their programming to consistently produce superior results. Which is not entirely surprising, since the very fact that they *can* produce more than 0.8bar shows that the programmer has superior programming skills. 0.8bar, as I've been saying for a while, is an OBD II "limit" of sorts. Without more complex routines, 0.8bar+ results in check engine lights and drivability problems.
Now that the factory itself is producing 0.8bar chips as stock (TT), it should be apparent that 0.8bar is *not* the safe limit of boost operation for the K03, and all the diatribes to the contrary were self serving. The factory *never* knowingly runs any component at the operational limit. There is *always* headroom.

RE: how do i find out what chip i have?
Basically... a chip doesn't just raise the boost and remove the speed governor. It has to remap the entire system of engine management. Therefore, the chip maker will have to include ignition timing and recycling, MAF reinterpretations, etc. These additional areas leave a lot of flexibility; flexibility which is why chip makers differ between each other. Ignition timing can be reduced or increased to complement the boost levels as the chip maker desires. It all depends on where the chip maker wants to program the curve of power.
TAP can have lower boost levels but still have sufficient gains in overall power due to other remaps - like advancing the ignition; these other areas may be maximized to increase power along the curve as desired.

I wish I could be accurate with this answer, but I usually deal in 1/4 mile times. You should be able to get around a 15 second timeslip for 1/4 mile.
Here's an interesting article that appeared May 1998 in European Car Magazine, written by Dan Barnes. It doesn't say what the 0-60 times were, but it gives great insight to what we've been discussing tonight.
