SLOWDOWN?

[MannysTurbo]

Hi everyone, thanks in advance on reading this topic, and any help you'll provide is greatly appreciated. About a month ago I purchased a 01' 911 Turbo, with 20k miles on it. I put about 1,000 miles on it in the first 2 weeks, just trying to really get a good feel for the car (and it was hard to stay out of it). About a week ago I began to feel like the car wasnt boosting the same, it just didnt give that thrust that it seemed to give in the past. At first I thought I'd grown used to the speed, but even after bringing a passenger in the car who was with me when I first picked it up said the same thing. It just seems slower. I took it to a Porsche dealership and they ran a full check on the car, and everything came up perfect. A friend of mine said that weather conditions in my area (rain, humidity, heat) can be causing this issue. If anyone has any idea what it may be, your thoughts would be really apprecaited cause im ready to rip the hair out of my head...I just miss the feeling...

Weather is definately a factor. The heat and humidity will slow you down a lot.

If you want more power, get a reflash.

thanks a lot man, i was really getting worried cause it was so drastic that i thought it had to be something internal...

can you elaborate on "reflash"? For us novices, what exactly does that mean? :notworthy:

Re-program the DME. Either with a factory program or a 3rd party program.

[MannysTurbo]

A reflash shouldnt harm the engine correct? Atleast if done respectively and correctly...?

[Loren]

No, if it is done by a dealer it will be a factory "approved" program. If it is done by a 3rd party - you are on your own (warranty wise).

[MannysTurbo]

Thanks for the quick response Loren. What can I really expect out of a reflash?

You should be able to see how much presure the Turbo´s are giving you. I would say around 0.9 Bar is normal with full throttle.

Hot weather and dry air will slow down the car.

gas quality will also effect this, the knock sensor will back up the timing and boost

I was thinking about getting a 2001 911 Turbo with 100,000 miles on it? Will that Turbo be substantially slower than one with say 10,000 miles on it?
