Either you can get irritated by this or think 'Hey, I'll probably see that guy again at the next light' (and you probably will). Most important. Did you rev all they way up to 6800rpm before shifting? If you didn't you didn't make use of all the power available to you. Unfortunately chiptuning for N/A engines is pretty useless. You'll gain 5 to 6 hp max, which you probably won't even notice, so that isn't an option. Same things have happened to me. My previous 9-3 was a 2.0 N/A with 133 hp. My current car is a 125 hp 9-3 TiD. It is so much quicker in every day driving, simply because of the extra torque.

Surely, Saab will use that engine sooner or later. That the one with the dual turbo set up right? (not twin turbo, because it has a small turbo for low revs and a large turbo for 'high' revs) The only thing I'm worried about is how long this engine will last. It uses over 2 bars of boost (hence the 2 turbo setup to prevent turbo lag). > However, I'm still old fashioned and have some reservations.

Because diesels run more efficiently they produce less CO2, far less CO and almost no unburnt HC's, so they are arguably cleaner then petrol cars. The biggest problem, the smoke cloud, is about to be extinct. The new Euro4 standard pretty much makes a particle filter mandatory for bigger engines, while the Euro5 standard is already being prepared. > Then the high pressure injectors must be very expensive > if something goes wrong. Engine component life depends greatly on the way it is used. I see more and more examples around of people that seem to think you do not need to let the engine get to operating temperature before they start using the power, which is a very good way to increase engine wear.
