Stay far away from that. As usual anything that seems too good to be true is. It fools the car into thinking it's running cooler than it is or something like that. Worse than fuel magnets 
Agreed. True performance parts are not cheap. So if you want cheap, do some exterior mods, b/c going cheap on the engine is a mistake.snork said:Yes, there are real ECU chips...but they will be sold by a "real" performance parts company, ie: Cobb, AEM, Injen, etc. They are also usually quite expensive...at least a few hundred dollars minimum.
There are no Tribeca specific performance parts unfortunately...the market is just too small for any company to spend R&D to develop a specific product. As far as I know, the only thing you can really add is probably a cold air/short ram intake since they're fairly generic and your just removing/replacing the intake box.
The K&N Filter should be sufficient, unless you are going for a true Cold-Air intake and move the air filter element outside of the enginebay, i.e behind the front bumper.webslinger said:hmm good info, so it is better to go with an aftermarket cold air intake or to simply use a K&N Filter in the stock intake system?
