From what I am reading, some say it is the end all be all. Some say it does nothing. Can it hurt the car? Guess it is only really good for '95 cars and before?

I have a 95 tip and didn't see a difference.

To the OP: you read and still want opinions? IMHO, don't bother.

Any chip --any, even the better ones-- will offer marginal felt improvement that the butt-dyno could confirm. And even then, that modest little bump is short lived since you will acclimate to this within the week. And this for the so-called "good" chips. Others can cause pinging and/or shift the power band such that you simply get the illusion of speed but really only lost power at the lower revs. You want power, buy a Camaro or whatever Detroit muscle, used ...very cheap these days. Heck, even today's Subies, Hondas, et.al. offer ponies that would embarrass many a 90s sportscar, and this from their mundane line.

The 993 offers so much as a whole package that is, clearly, aging and needs addressing. Focus on the essentials of an older car and it will feel new. Suspension, rubber bits, a more aggressive alignment, tires!! ...so much one can do to make this fabulous icon fresh again that will --will-- make for genuine, lasting improvements that will easily put a smile back on one's face. Maintain the 993 --updating aging pieces-- and enjoy it for what it is: a superb example of automotive engineering and sportscar feelgoods straight outta the 90s. Who needs 2.1 gigawatts when you have a 993 as a time machine. Just sayin

Dyno charts from Steve Wong show a lot more than "felt" butt.....

Wong chips with test pipe and sport muffler increases HP and torque om 3.2s. Plus, smoother idle and higher set RPM levels.

Basically you can get a Euro tune for your US spec ride with a few minor parts.

Facts matter.

Go to Steve Wong Chips website for lots of data.

All true^^^; and nothing in the way of marketing, from a website that is trying to sell performance chips.

If you want more power, install a supercharger and intercooler.

Edward captured the essence of our cars in his post above.
Or, if speed is an absolute need, re-gear, go to a 3.9 or 4.0 for many 10's of thousands.
Chips. re-flashes, exhaust mods...seem like a perennial desperate quest for the Holy Grail.

I was skeptical, but now that I have a chip I really appreciate it. Small but noticeable bump in power but more importantly it is more responsive and a smoother pull through the rev range.

3.2 Euro vs 3.2 US car.

Euro cars have more HP and Torque

Why?

No Cat, sport exhaust and different tune/chip used by factory for Euro cars.

Take your US spec 3.2, delete Cat, add Sport Muffler and Chip to match Euro tune with new parts and you have more HP and Torque.

You naysayers should call Steve Wong a lair to his face. Saying his research if fraud (dyno charts on website) is unwarranted unless you have dyno charts on his set up you'd like to post.

Old discussion with appreciation on both sites of the spectrum....
some hardliner here trying already to make themselves to Exorcists in this regard by carrying their vendetta from tread to tread ...

reading some of the old treads might help...

And, as you specifically mention Steve Wong chips

The best is allways your own impression, so try it and if you don't like what you got send it back to him and you will get your money back, no questions ask.

The old NA chips debate. I remember them well from my BMW days.

Same arguments, different place.

Our cars have fixed valve timing so the impact of software changes will be small, incremental and for most drivers a poor value

Lorenfb

The reference to timing is ignition timing, not valve timing, in the 993 and earlier.

Great answer! All of the answers helped shed some light actually. Thanks to all that responded.
