Ok... How many Steve Wong Chip users are out there?
 

I'm considering one and want to know if this is one of those "it's awesome when I read about it but I personally can't feel a difference". Subjective, I know. It seems like a great modification. Comments? Is it worth it to you? Thanks

I noticed a significant difference immediately. The car is smoother in the mid-range, and has more on top.

SW Chip
 

If you like more MPG,Quicker throttle response and a little extra HP go for the SW Chip.
Otherwise stay with what you have ; )

I even went to a Porsche specialty shop in Michigan, and the mechanic there said "You need a Wong chip".

That pretty much sold me on the chip....

Makes an improvement for sure. I am not going to tell you its like putting a turbo on your car, but my car ran and idled much smoother after the install, and did notice probably about 10% more power. But I really like how much smoother the engine runs!

GL!

One of the best purchases for my 3.2

cat delete & wong chip on my 3.2. When I swapped to stock chip and cat for smog check, the car felt lethargic in comparison.

Dude, search and you will be overwhelmed with positive reviews!

My cars got a receipt for install of a WM Chip. I'm assuming this is a Weltmeister but haven't taken out the box yet to confirm. I'm only going through the effort of taking the box apart if I would be convinced that it's worth the money to upgrade to the Wong Chip over a Weltmeister. If not, I'm not going to touch it.

From what I've read on here, it's pretty well known that the Wong chip is the way to go. But for my purposes I'm leaning to leaving it with the second rate chip which is still better than stock.

Exactly that ^^^. Even my buddy who hadn't been in the car for a week, immediately said "what did you do to the car". It's that noticeable.

Not only does it give a marked improvement in driveability but steve backs up what he sells and gives great cust service , called him one day to ask a question hoping to leave a message and he answered his phone ON A SATURDAY , i told him i would call him back but he insisted and answered my question . very professional and knowledgeable . He will also re-chip for a nominal fee if you make modifications to your car.

In the Porsche Owner's Club, just about every new race motor in V3, V4, and JP go to the dyno with Steve Wong before it's first race, certainly with the Aase guys. It's the first upgrade I do to a car.

I bought a 3.2 liter motor three years ago and brought SW to the dyno with me. The first run was 202 HP. When we left it was 226. That took a couple changes in exhaust configuration, but he had me to 218 with just his fingers on the keyboard.

I'll echo the thumbs up; very pleased. I went from the original chip to using a Weltmesiter for a number of years, and switched to Steve's chip almost 2 years ago. Performance (as measured in lap times) saw a definite improvement, I had no issues passing smog with it installed, and rough idle issues that I sometimes saw with the Weltmeister have been non-existent with Steve's chip. So while there's always a YMMV sort of thing to anything like this, it seems like a well developed product with alot of care taken to get things right and I'd consider myself a fan based on my experience with the product.

It works. Make sure the throttle is fully opened and the brown wire pin is disconnected.

Well that is a lot of convincing statements! Thank you!

It's a no-brainer. Great product and great support.

^^^^this^^^^

I live in LA, Steve does too. I brought my car to his place on a Sunday morning and he and I blasted up and down the 101 freeway on an early Sunday morning. He plugged his laptop into my car and data logged it. He then burned a chip for MY ROW with a cat with 91 octane CA gasoline. It helps the mid range lulls a lot. It also passes CA smog. When I first bought the car my brother drove it, a year or so later with the SW chip he drove it again and he said "Did you tune this thing up or what". Its not like night and day, but its a definite improvement. Worth every penny.

Apparently all of you Steve Wing fans have bought into a myth and only think you feel a difference. Look here:

In France ( SmileWavy) , we have lot of SW fans too (SC , 3.2)

Go for it...more low end also, as well as mid and high

Go for it!! I have the SW chip for 93 octane fuel with the stainless M&K cat bypass, and factory modified airbox (lid opened up) with the paper filter. Great low, mid and top end pull, great sound and fantastic fuel mileage to boot. Steve also offers the best customer service I have ever had the pleasure to deal with. You wont be disappointed.SmileWavy

I put one in my dad's 88, which I drive frequently.

Steve provides great support. After opening up the ECU on the car I found it had a replacement box with the wrong factory chip for an 88. I called Steve and he walked me through how to determine what was in the car. He then offered to exchange the chip for the correct one at no charge.

The chip deffinately improves drivability around town. I don't think it makes the car much faster, just more satisfing to drive around town. I think there is a little bit of hype surrounding these chips, so I was expecting a little more of an increase in power than I felt. Either way, it was money well spent.

I would describe the 88 as sluggish at low RPMs before the chip. With the chip, I would now describe it as peppy. I added an M&K cat bypass and it increased the overall power just a tad more. The 88 still can't keep up with my 81 though :D

Thats exactly what i found with my 85, i had a 1979 SC before it, and it definately felt more lively than the Carrera, i was quite disapointed with its performance, and it was hard work to drive round town and in traffic.
The reason i spoke to Steve W and decided to give his chips a go, i wasnt expecting any aditional power just better driveability, i was a mechanic for many years and built Tarmac race cars etc, so i know there isnt anything magic going on just plain old development time and experience in knowing what parameters to change within the MAP to gain the desired results.
Anthony,TD...

Yep Have a Wong chip, and cat bypass.
Really like the combo.
Never switched the chip for emissions CAT yes. Never failed either.

It's great that we have one guy playing devil's advocate here, BUT...I have sat next to Steve Wong looking at the dyno readings while Sergio Nardi of Game Face Motorsports put my car through the dyno runs. I've seen the before and after graphs and charts, three times. Once after buying a 3.2 for my race car. Second time after a rebuild. Third time after electrical problems forced a replacement DME. On all occasions SW was able to squeeze out an extra 10-15hp. Even more the time I brought in a couple exhaust configurations with me.

Beside that, he's one hell of a nice guy.

I think the SW chip made a difference...better idle on start-up and more power. I also did all of the recommended maintenance including O2 sensor, spark plugs/wires, valve adj, distributor cap/rotor, clean distributor, MAF adjustment, throttle check and full throttle check. I also dropped about 200 lbs in unwanted weight which always helps.

I think the best choice is to get a custom chip that you can measure and get the air/fuel ratio checked. This way you can tell if you are getting improvements.

Steve will be the first to tell you, every one of these motor breaths and fuels a little differently. You will always get a better result if the chip is custom programed while on the dyno.

Regarding his over-the-counter chips, Steve has enough data on these motors, over a long enough period of time, to create statistically significant conclusions to optimization of air and fuel ratios. His OTC chip is not like putting a supercharger on your car, and you might only feel an incremental improvement, but the guys running the POC PDS program see the difference in lap times for sure.
