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

Don't beleive the hype.

Even if you are talking about the N/A 2.5 gt 97-04 into a 2.2 L you won't get much difference. Could be worse due to the 97-99 are dohc not sohc. If you meant the 05 GT chip that's a bad idea. What year/engine Legacy L ?

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.
