Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Interested in a 3.4l c2 6sp Three questions. 1) What is the stated MPG? What is actual MPG? 2) What are the options for tuning the ECU. 3) Are there any ducktailsl available for the 996 other than the one from the Ruf RGT. How much is the RUF ducktail available for? (without the larger add on spoiler) Well, I guess that's technically 5 questions. -Ben Martin

I get around 22-23mpg when I'm doing about 80mph. I get about 18mpg with combination city/highway and somewhat aggressive driving. It'll get easily over 25mpg if you're going the speed limit.

I have tried hard and cant get mine below the mid-teens... some people are able to get as low as 9 or 10.. That's what I am talking about!!

Ha, on my old mill, drilling some holes in the block would be a cheaper way to get it to EXPLODE !
When I drive like a little old lady I can manage about 18mpg city, otherwise 12-14 is my norm. Like Medtech states, mileage is a non factor in this type of vehicle.
The 3.4 had 28 mpg highway rating when it came out, pretty amazing, but you've gotta drive it steady to get that, no spurts to 120, ha. But yeah, I think you need to come up with 3 better questions.

Pthh, no one would ever "spurt" down to 120... OHHHH - "UP" to 120

Yeah - it's pretty crazy to know that you haven't even used up all of 4th gear at this point, and 2 more gears to go.. Many times when the road opens up for me, I'll blast off and run through the gears, and am always amazed at how it can push me in my seat - even in the triple digits. This thing is a highway monster.
I got 28 on the highway driving it back from NC when I bought it. This was a constant 65-70mph and I got 28.4 mpg on the read-out. With me driving medium (some quick starts and some normal driving) I get about 22.7 according to the readout. Not bad considering the kind of performance this car offers,
Mine averages 18.5. If you want mega-fuel economy, get a Toyota Pious.

Better questions like... what oil to use... how long do the 996 engines last, etc, etc.
'99 C2 no engine/exhaust mods gives me 18.7-19.0 mpg as a DD, with relatively "spirited" driving/passing and no cruise control. My max was driving 400 miles down from Oregon I managed to get 24mpg but that includes some 140mph spikes mixed with cruise control at 70mph.
I average 23 mpg regularly...but who cares about that? Most would tell you that an ECU upgrade will not produce noticable power improvements, however combined with exhaust,ECU,and an aftermarket induction you may see better results, but not really significant.
