Computer Flash?

[mcvgums]

I've recently installed Fabspeed intake, and I have ordered the mufflers for my 1999 996 C2. Is it beneficial to have the shop flash the computer?

Flash it to what? There is only one Porsche DME program for a MY99 Carrera.

If you mean buy an aftermarket chip - then my only advice is to choose a shop that will give you a dyno run from your own car - proving the before HP (at the rear wheels) and after HP (at the rear wheels).

Thanks Loren, the shop said that I will not get all the benefit from my intake/exaust unless I do the $1400 computer "flash". They must be talking about a chip, what kind of improvement might I see or feel?

The most realistic performance increase will probably be the weight loss associated with the reduction of your wallet by $1400. Most computer voodoo is just that unless you have *significantly* changed the intake parameters (i.e. cams, turbo, supercharger, etc.) I think the reason that Lauren suggested a before/after dyno run is because most of the time, there isn't anything gained in this area. Even where there are some gains, it is my experience that there is merely a shifting of the peak without any increase in the area under the curve and in many instances, there is actually a reduction of the area under the curve. Like I said, mostly voodoo unless you have really changed the engines flow characteristics with something more than a 'free flow' intake or exhaust. Just my two cents. :soapbox:

I agree in my past experinces I really havent noticed much of a change with intake exhaust and a chip. You do get a gain but its not much. It will sound faster though :) In turbo cars you get a huge gain from a chip since you can up the boost.

Is there an improved throttle response with the intake/exhaust/chip combo?
