since its last spark plug change, you will need
to change the spark plugs now before test
driving the vehicle.
C. Check all fittings, nuts, bolts and clamps for
tightness. Pay particular attention to oil and
fuel lines around moving parts, sharp edges
and exhaust system parts. Make sure all
wires and lines are properly secured with
clamps or tie-wraps. (See Fig. 11-a.)
D. Check all fluid levels, making sure that your
tank(s) is/are filled with 91 octane or higher
fuel before commencing test drive.
E. Start engine and allow to idle a few minutes,
then shut off.
F. Recheck to be sure that no hoses, wires, etc.
are near exhaust headers or moving parts
and for signs of any fluid leakage.

11. FINAL CHECK
WARNING: Due to variances in each vehicle,
Vortech recommends that the vehicle
get a “custom tune” from a local, rep-
utable tuner.
This kit is supplied with a “universal”
fuel and ignition timing calibration. This
calibration is intended to allow the vehi-
cle to start and operate at part throttle,
and is not optimized for full throttle
performance. Do not operate the vehicle
at heavy throttle or high RPM until a
custom calibration tailored for your
specific vehicle can be obtained from a
competent tuner. A “wide-band”
exhaust oxygen sensor must be used to
confirm proper air/fuel ratio. Vortech
suggests a proper WOT air/fuel ratio
range of 10.8-11.0:1 for 91 octane fuel.
WARNING: Never operate your engine at full
throttle when the engine is cold.
Always allow plenty of time for the oil
to reach full operating temperature
before running above 2,500 RPM. Full
supercharger operating temperature is
generally achieved only after the
engine water temperature has been at
the normal indicated operating range
for two or three minutes.
