Helpful hints and F&Q’s (READ THESE)
1. Clean your filter every 2,500-3Kmiles for optimum performance other wise every 6K is fine.
(See website for instructions for cleaning filter.)
2. Do not attempt to place the scoops anywhere but where we have them, this spot was measured several
times (we even put them directly behind the grill during testing, we tried several styles) where we have
them is where they work best. They use the raidiused edge of the radiator that is smooth to increase their
overall area and it offers a safe package for deep water as well.
3. This kit can be used with any programmer or custom tune. Feel free to contact us direct for optimum tun-
ing as we have used them all and even custom tuned as well using EFI- live.
4. Some will not need to reset the ECU by disconnecting the Negative end of the battery. Your vehicle will
learn the new airflow over time, usually 100-200miles, some may require the ECU to be reset, we had 6
test trucks and 4 out of 6 did not, they learned within 100miles or so. If you have any type of programmer
you will not need to reset the ECU simply fine tune your programmer- call us direct at 713-477-8100 ask
for our tech department because some programmers were more aggressive than others and we can help you
fine tune the system.
Tech Note - Important for custom tuning
Tuning using any aftermarket programmers- call us direct 713-477-8100 for info on this. During static
dyno testing we witnessed “EVERY TRUCK” range from a 15.2-14.1 airfuel at idle to a part throttle 12.5-
13.2 to a wide open reading of an amazingly rich 10.0-10.7 airfuel ratio in stock OEM form. This included
all 4.8,5.3 and 6.0 trucks. All of these trucks and SUV’s have a huge amount of torque management, some
of this is removed by the programmers, but for those of you who do dyno, watch your airfuel ratio when the
converter really comes in. We like to see static WOT airfuel ratios of 13.2-13.5 for better mileage the ECU
will fine tune the rest.
What to expect and how to use it best on the road
Throttle response and low end power is the 1st thing you will notice. You will also notice that you won’t
need more than 1/4-1/2 throttle to move the vehicle at any decent pace, going to full throttle immediately
will not do much because of Torque management –(its job is to avoid you shocking the driveline by put-
ting to much Torque to quickly to the tires) it will suck gas like crazy when you do this unless the truck has
been tuned by use of a programmer or a full custom tune.
½ second drops off of 0-60mph time and .3 and +3mph in the ¼ mile times are the norm.
