is it worth fitting a performance chip to a 997

993tt - Factory chip upgrade 430bhp
993tt - Factory chip upgrade + larger turbos & extra oil cooler 450bhp
996tt - X50 option, Factory chip upgrade + larger turbos & extra oil cooler 450bhp
996gt2 - Factory chip upgrade + larger turbos & extra oil cooler 480bhp + other mods

Because it puts more stress on the engine and they have struck a balance between reliability and power. It is easy to make a turbo more powerful by just upping the boost and fueling. With an NA its bloody hard & expensive.
Actually had a chat with Gavan Kershaw of Lotus about chips on NA engines and he was very dismissive.

wish I could agree however I reckon power is decided by the marketing dept at Porsche these days rather than the engineers!
Surely the accountants then swoop and arrive at the minimum spec parts to then support that power?
As mentioned on the other thread about turbos, it's fashionable these days to have very flat torque curves on turbos and limited boost, all to improve drivability, I guess that makes it easy to unflatten it a bit

there's room in the standard map to run more boost in counries with decent high octane fuel available, porsche has to set them up for the worst case? just a guess[/quoteyouralmost right it's all to do with octane and servicing..because cars are sold in alot of different countries the manufacturers choose a mid range trade off between max power curve and min power curve, also if the car isn't serviced on time it won't effect the engine as much in respect of wear and tear....I've just spoken to Superchips about my car and that is the answer they gave me...also rechippin a car will not damage it because in most cases the fuel consumption and smoother running can make the engine last longer, because you have more torque it takes less fuel to reach the desired speed, so less wear overall<<,and no quotin me about rechippin not damaging the car I'm an IT consultant not a race tuner lol hope this helps
As an IT consultant you're possibly familiar with 'testing' - consider the amount of resource expended by the likes of Porsche in testing their 'chip settings'. Compare this to so-called chip companies who offer a chip for pretty much every model under the sun - how much testing goes on there...
