I recently purchased a 2008 911 Turbo and have a problem. When I really push it, particularly from low to high speeds quickly I get a 2 second lag before it accelerates. Of course when it finally does kick in I get all 480 horses at once, making it quite a challenge to handle. My previous car was an E55 and I loved it. It was never at a loss for power. I read in Car & Driver this lag was some sort of software issue. The dealer says it is the normal turbo lag but 911's are famous for not having turbo lag. Does anyone have a solution?

Replying to: bayareafx45 (Mar 06, 2008 11:26 pm) The reason your vehicle lags actually has to do with several factors. I agree that Porsche over the years has done a great job with turbo lag, and you are correct about the software. The amount of lag is determined by how much force the turbos' create. The software accounts for this as the vehicle accelerates, but as Porsche developes new technology, those turbos' grow larger in size and the software can do only so much to correct it. So they do have a bit of lag and thats perfectly normal. If you like, TechArt and some other companies may offer to re- map or re- program you electonic control unit (ECU) so that it performs better. It will upgrade your top speed, shift points, turbo response, engine respone, improve gas mileage, and so on depending on what your looking for. |

I'd like to add that I am in awe of you fine folks who can afford to buy these vehicles. It has been a dream of mine to own a 911 since I was three years old, and alas I will probably never be able to. I am truely envious of each and everyone of you. I look forward to servicing your cars and I hope you'll stop in and say hi sometime when you take your car into the shop  thank you for giving me a small hint of these amazing cars!

As to never be able to own one of these beautiful automobiles....the rule is......Never say Never ! You seem to be a smart and intelligent man and you really know these 911's. This will pay off one of these days and maybe I will be in awe of you at the Porsche Club meets !  Keep posting and thanks for you tech. knowledge info. !

| As far as I'm aware, they only modified the engine slightly in the new 997 models. I don't believe they changed anything with the turbo's which could be why you see some lag, but like most drivers, it depends on your habits when you shift and accelerate that will give you lag. Air quality, altitude, temperature, all these things and more make a big difference when you are squeezing that much power out of a small six cylinder engine. | |
