I'm in So Cal also, where is Powerchip located? I was thinking of going with the Revo chip myself, but that sounds pretty nice if they are taking care of you and the price is actually less than the Revo re-flash. Although the Revo is done by my local Porsche mechanic and so they would probably take care of me also. Fun stuff!

They're located in West L.A.

I have a 987 
Powerchip is appealing because it comes w/ a warranty AND a guarantee for a good price.

Hi,
There are several ways to chip a car. You can add additional Maps, you can piggy-back on the OEM ECU and overide default Maps when certain parameters are experienced, or you can trick the ECU into seeing different conditions than those actually present. Some of these are actual hardware chipsets while others are merely a code over-write.
It is more difficult (therefore more expensive) to break the OEM code to write additional Maps (which are tested to work properly) than it is to create hardware/software which sends false sensor readings to the existing ECU.
I have not researched whether or not these chips differ in this manner. Also, each company's market research establishes the price point people are willing to pay and they price their products accordingly...
Happy Motoring!... Jim'99

Jet Performance, re-writes the code. That's why they require you to send in your ECU and then they overnight it back to you after they are done with the changes. That's the same thing that PowerChip does. So why is it better, if it is at all?

Hi,
First, without trying to start any flames, I've rarely met anyone who spent $600 (or such) on an upgrade who's own personal Butt Dyno didn't confirm the money as well spent, not casting aspersions in any way, but don't consider such reports as truly reliable.
But, on point, as the power and torque curves change through the RPM range from the upgrade, the shift points can change (early or late) as a result. Hope this helps...
Happy Motoring!... Jim'99

Can idle rpm change?
I think that would affect engaging 1st gear from a stop.

MNBoxster thanks for better explaining the shift points that I was referencing on being smoother.
You said it best, but, on point, as the power and torque curves change through the RPM range from the upgrade, the shift points can change (early or late)
On the reliable comment, just posted what the vehicle seems to do in comparison from when I drove it of the dealer lot and the past eight months.
Dyno meter is the best way to go but for the price I paid felt it should be done once the headers are in and it has been re-flashed.

Believe or not, hp is not what I primarily want from REVO.
I was planning to get Sport Chrono. Some people call Sport Chrono a gimmik, but I liked it. (Not the watch on the dashboard though).
Well not after I had a chance to drive REVO'ed 986 for a day. I have to admit I was very impressed with REVO. With added hp if any, I call it Sport Chrono with steroid for the same price or less (and no watch). No I don't buy "Less PSM" argument.
I'm still on the fence because of lack of information on warranty and emission issue. If somebody have experience or more insight on that, I'd appreciate any comment.
