Former 2.0L fixed Cyclone experienced customer, bring his another car,
Before fix Cyclone tested, and rather good function except brake performance.
After fix Cyclone after Air Flow Senser, 2 unit, and 1 unit at exhaust pipe, after catalitic converter, in test driving , improved performance and braking power.
Why? improved vaccume in surge tank after throttle body by Cyclone.
Even though good maintenance it'll much better if it used Plasma plug.
