Well, first of all my question the same???? I did find this site
www.turbonator.com they said it will increate up to 35HP, Is anyone know anything about this
Turbonator's airflow dynamic or used it?
And for better gas mileage:
my 96' ranger 2.3L was run with 17-20MPG
Now it do with 20-23MPG after I replace new (Motocraft parts) Spark plug and wire, Idle valve and Idle sensor (Idle on my is stuck lot of time the RPM go up to 2000-3000RPM at Idle) and air filter.
