Horsepower

[95ExplorerLtd]

I've got a 4.0L OHV, and how many more horsepower do you think these mods would add?

throttle body
V6 headers
mass airflow sensor
K&N air filter
drilled airbox
jet module (maybe)
borla cat back

I read an article in Truckin' mag once where they put headers, Flowmaster w/2.25" pipe, KKM True Rev and a superchip on a 4.0 Ranger. They dynoed a 22 horse gain at the rear wheels with an 18 ft/lb increase of torque. So, you know, a reasonable 25-30 horses at the wheels or so.
