Legacy GT ECU chip in Legacy L


Recommended Posts

a guy at school whos father manages a subraru dealer told me to get one, itll reduce MPG a little but give around 20 hp. i can get one for around $100

 

does anyone know much about this or how much it will help?

There is no way you'll get 20hp from a na 4cycl motor from just a chip.

Don't beleive the hype.

Chips cannot produce that kind of power hike on a NA engine. Period.

 

Even a turbo motor would not do well with only the chip.

 

Reason is simple: The chip cannot change the most important aspect, namely valve timing.

Also, the injectors are unlikely to flow accurately if you demand them to flow more fuel.

 

A NA chip tuning will involve the chip, new injectors, and ideally new camshafts.
