I need more power too. This thing is insanely slow for 275 hp and 295 tq. Although I haven't done so yet, you can try some new air filters. For roughly $100, you can get a pair of Greens or K&Ns, but some have reported problems with the K&Ns due to the oilyness.
The next thing would be to reprogram the ECU. You're on your own for this one because some have run into troubles but others run them just fine. Consult Powerchip, Renntech and does Kleeman do them too? The service usually ranges from about $1000 to several grand.
If you want to take it farther, supercharge it. That would give you a lot more power, but at a price. Let's start with air filters first.

Thanks!
Thanks!
ECU remap will get you 10-15HP peak but more response in the midrange for about $1000. Air filters might gain 1-3HP peak and do nothing in the midrange for $100. Removing the secondary cats, resonators and swapping out the mufflers might get you a few peak HP but you will likely lose a little bottom end and midrange power, all for about $1500. Cams will add about 15 HP but cost about the difference between a 430 and 500 would have been. Supercharger can run up to $20K installed but provide the biggest bang across the entire RPM range.
If you wanted more power, you should have bought a 500.

Off the top of my head you have a few options.
RENNtech: 10hp 12lb-ft torque - 1595$ (Just ECU tuning)
Brabus: 30hp 18lb-ft torque - 3995$ (Camshafts, vavle springs, and spark plugs)
Powerchip: 19hp 17lb-ft torque - 990$ (Just ECU tuning)
You can get those products from our sponsors. www.euroteckmotorsports.com and www.evosport.com
Have fun!

Thanks for the help. I had a S500 99' It was so much faster then this 430.
I'm not sure what the HP range was on the 99'
I think I will change filters and do the ecu to gain HP.
Where the best place to buy the body kits? Front bumpers skirts etc.
