When the topic of air cooled 911 tuning comes up on the forum, there is one name that comes up every time...Steve Wong at 911Chips. For years we have been including his DME chips in our full performance packages for the 3.2 911, and have been nothing but thrilled with his work. We now offer the Steve Wong 911 DME Chip Upgrade separately on our website, so for anyone that is interested in pursuing this upgrade, please feel free to reach out to me any time. Below is some information taken from 911chips.com to give you a feel for the upgrade.

"Performance DME chip upgrade improves horsepower, torque, and driving characteristics by reprogramming various sensor inputs, air/fuel ratios, and boost pressure (if applicable).

Available for all 911 Carrera 3.2 models 1984-1989

Not just another one size fits all' performance chip. Hundreds of hours of code revisions and road and dyno testing on over a hundred Carrera 3.2s have unleashed new pockets of performance previously undiscovered - performance unavailable from anywhere else. No one else has even come close to the amount of research performed on chipping the 3.2 engine. Guaranteed to outperform, all chips have a 100% satisfaction guarantee. With a wide matrix of chip programs available to suit a variety of engine performance modifications and owner preferences, the most popular are listed below. This insures the optimum setup for each particular car.

Programs are available for both the catalyst spec U.S. motors, and the Euro/ROW spec cars. All programming for US version cars by default is for 91 or higher octane fuel. If programming for 93 octane fuel is preferred, please note your octane preferences. For Euro/ROW spec cars, default chip programming is for 95 RON octane fuel. If programming for 98 RON fuel is preferred, please note your octane preference.

The following runs are from an '87 Carrera 3.2 performed on a Dynojet 248c. The motor is a completely stock U.S. spec 3.2 with the exception of a euro premufflerr. The red curves are the car initially dynoed on the stock chip, showing a maximum of 188.6 SAE rear wheel hp (rwhp) at 6000 rpm and 174.9 ft-lbs torque. Calculating for a 15% transmission loss (rwhp/0.85) the motor produces 221.8 HP at the engine. Subtracting for the approximate 6-7 hp gain of the premuffler, that comes close to the factory 214 SAE (217 DIN) hp rating of the car.

With the retuned performance chip for 91 octane pump gas and the premuffler, the motor now exhibits a much more power optimal air/fuel ratio, and redynos a maximum of 206.3 rwhp at 6200 rpm and 184.0 fb-lbs of torque, as shown in the blue curves. At 6200 rpm, compared to the 182 hp the stock chip makes, that is a 24 rwhp gain (29 hp gain at the engine). Calculating for a 15% transmission loss, the engine with the chip produces approximately 243 HP at the flywheel."

Love my wong chip.

That's what I like to hear!
