I just got a 99 Saab 9-5 the other day. I've already put an air filter on it, and the next mod i was thinking about doing was putting on a modified APC.

http://www.group9performance.com/saab.asp its on that page about a third of the way down.

has anyone else done that to their 9-5? Just let me know what you guys think. Thanks.

That won't work with a Trionic car like the 9-5! I believe that is only for the classic 900.

If you want more power you need an upgraded ECU or a PPC (http://www.partsforsaabs.com/bsr_ppc.php)

i looked at that site, and i have two questions. first of all, what is the difference between an ECU and a PPC. Secondly, I live in the US, so how exactly do I pay since that site is in Euros?

You should have really read this board through first. The ECU is an "Engine Control Unit" located in your car -- it's the computer that controls the engine. PPC is a "Portable Program Carrier", a small device used to update the software in you car's computer (ECU).

US customers can go here (http://www.genuinesaab.com/) or here (http://www.engstrom.net/).

You can order the same as on any other e-commerce site...

Just select your currency from the menu on the right of all pages. Don't forget that customers from outside the EEC do not pay VAT, you need to log-in to remove VAT from prices.

I think you will find that PFS (http://www.partsforsaabs.com/default.php?cPath=28_270_292) is the cheapest for the PPC upgrades.

From the performance standpoint, there's no difference whatsoever, as both would carry the same software.

If you order an ECU, you get a complete replacement for your car's original ECU. It will be pre-programmed for your car, containing the new software. You'll have to arm yourself with a Philips screwdriver and a 10 mm socket wrench, pull the old ECU out and bolt the new one on. Usually, if everything goes OK, you mail the original unit back, but you can also keep it (after paying the core charge), in case you'd ever want to restore the car to the original settings. The ECU itself is a heavy weather proof metal case, size of a good book, with a circuit board inside.

If you order a PPC, you get a small device designed to update the software in the ECU that's already in your car. You won't have do disassemble or unbolt anything, just connect the device to the OBD-II port under your steering wheel, press a button, wait 20 minutes and enjoy the newfound power. PPC allows you to go back to the original settings or tune the car again anytime you want -- it just changes the software in the ECU. If you ever decide to tune your car further and install more capable hardware, you can pay a reasonably small fee and receive a new version of software for your PPC, which would match your upgraded engine better. PPC is slightly bigger than an audio cassette case:
