I have a 2005 Chrysler Sebring with a 4 cylendar engine.Gets great gas mileage but no power.

Question

Does anyone know how to increase the horsepower via the onboard computer or anything that will increase horsepower a little bit. You have to wait until no traffic at all is coming before you take off. I live in a rural area of East Texas & its mostly highways here. All help is appreciated

Answer 1

Well...aftermarked exhaust, air intake, turbo/supercharged, higher octane gas?

Answer 2

make sure all cylinders are firing

also

get a bigger engine

Answer 3

synthetic fluids in the engine and trans will reduce friction increasing available power.  a high flow filter like a 'green filter' or a 'k&n' will help a little.  a new exhaust, cat back, will help as well.  the chip can help too.  if you are careful and look for the CARB certified ones you won't even affect your warranty with these upgrades.
