Steve Wong chip
 

I just wanted to report that I installed a SW 93 octane chip in my 1988 911 3.2 cab and I am very pleased. I had already installed a cat-bypass pipe and noticed an additional noticeable increase in low and mid-range pull once I installed the chip. I also discovered that the brown wire was connected, even though my car was a Colorado car; it is now disconnected. While the chip is a little pricey, the extra punch and smoother running is worth it to me.

I concur.

Yup. It even works in Sweden. :D

it's been said a million times... sw chip is really really really nice addition!!! i would pay 3x the price-- im not rich either- it's just worth it- best bang for your buck! sw chip and a nice exhaust set up-
