Save your money, the chip is a ohm resistor at Radio Shack for under $2.00. It splices in to you IAT wire harness located at the intake tube between the air filter housing and throttle body.
Problem with this system is, that you can not adjust anything and have to run a constant 91 octane just to make sure you do not have a Detonation. The ECM will catch the Detonation from the knock sensor and compensate for it by retarding the timing which in turn lose of HP till next start up.
If you like and don't mind the check engine light on once and awhile, you can do the same by just disconnecting the IAT wire harness which give the ECM a 0 resistance thinking it's -20 out side and turn the timing up and lengths the injector pules.
When i was running a Nitro in the Toy before i sold it, i had installed a 10K ohm Potentiometer which you can buy at radio shack for under $5.00 i believe, I just spliced it in to the IAC wire harness so if i wanted to play with the Nitro I'ld turn the resistor up making the engine think it's 185 degrees F and would ****** the timing so i would not hurt the engine. But if i wanted to get more timing i would just turn the knob to drop the resistance to get more time since the engine thinks it's -20 out side.
Hope this helps. Keep me posted if you need more info. Best thing is to do a dyno tune and you can change everything right down to the Shift points.

This will not work.
There are no electronic chips in existence that are designed for use with any model of GTP.
If you would like to work with electronics only for performance changes you need to either reprogram your PCM yourself or purchase one that is pre-programmed to be compatible with your GTP.
However, the good news is that you still have a few options, depending of course on the current set up of your GTP.
Regarding that I highly recommend that the only source you visit is http://www.zzperformance.com/grand_prix/products.php?id=107

Well, to answer the question you asked, one would have to know what kind of vehicle (YEAR, MAKE, MODEL, ENGINE SIZE) that you are attempting to install this in.
With all that said, my recommendations are DON'T DO IT! You are opening a can of worms that you will most likely no be able to afford in the not-so-distant future. I do not know anyone that has installed this aftermarket junk and not regretted it later.....However, that is just my professional opinion....do with it as you please.
