Re: Before you give your car to a Tuner, watch this VIDEO The BIGGEST mistake enthusiasts like us make is to think that OEM's engineers are fools & do not know how to tune. THAT, friends is VERY far from the truth. The kind of resources & money they spend is VASTLY beyond anyting you and your tuner could afford. It's just that they work under far more constraning & often opposing requirments, like noise emmision, pollutants, smoothness of performance, transient response (on-throttle, off throttle), in-cabin-noise etc. They also make the car as people friendly as possible. This means increased oil change intervals, increased milage between servicing etc.
When you go to get more out of your car, you invariably compromising on SOME factor which the OEM engineers did not have the luxury of having.
Having said that, tuning can be a very satisfying experience if done right. BUTTT, getting it done right is a tedious & expensive process which takes a LOT of time & money. In fact, engine tuning in modern cars is VERY tough. You think a single dyno session is enough to get you a car which is fast, smooth, has good transient response, can be driven in ALL weather conditions (hot, freezing, altitude etc)? This, when OEM engineers spend THOUSANDS of man hours tuning the engine in the car you buy? Think again. In fact most of the stories that DO NOT come out on these forums is that MOST people sell off, or otherwise go back to OEM, after a year or two of having these highly modified cars. Why?
I believe the answer is:
1. Stressed engine parts cannot take the stress & fail prematurely.
2. There is a lot of upkeep required with oil & filter change intervals & other parts.
3. The initial tuning of the piggyback was done more for horsepower than overall power accross the rev range. Chasing hero horsepower like this results in a power-band that looks like a mountain side. It is very steep. This affects driving very badly indeed. That car will be a rocket in a 500-1000 rpm band, & a pig to drive everywhere else.
So, the key to good tuning is to keep it reasonable.
