Does PMAS intake work
Well i have put in 15 timed runs today. 5 runs on a dirty K&N filter, then 5 on a cleaned filter and stock intake box and then 5 runs with the PMAS installed.
Mods to my truck were prior to intake are:
4:56 Yukons gears
K&N drop in filter
Magnaflow side exit exhaust.
BDX Tuner with 5 Star Performance Tunes
Also note this truck sits on a 6 inch lift with 10 inch wide Fuel wheels wrapped in Toyo Open Country RT 35 X 12.5 x 20.
Runs were performed in 87 Performance/Tow Tune
I threw out the fastest and slowest runs of each 5 and took the average of the 3 runs. Most of the gains took place from 50 mph to 100 mph.

1/8 9.6 @ 74 mph 9.5 @ 74.5 9.4 @ 75.7 mph
Is this mod worth the money and gains. No not really but i think this intake would perform better with a Boss or ported 18 manifold and long tube headers then i can see the intake being beneficial. From the acceleration data you don't see gains until the higher speeds where airflow is more critical. With a higher flowing manifold and long tube headers this intake would see greater gains than the stock air intake.

Thank you for taking the time to add constructive data to this forum! It really is appreciated by me and I’m sure many others. Can I assume these tests were done on your 2016 5.0 super crew 4x4?

I was making an attempt to keep all things on an even playing field so the results could be duplicated more easily. I put a lot of effort into this I even went out measured the distance and marked it. Do you know how hard it is to find a set distance thats at or near the same elevation for the distance i needed to measure. The results are about as real as one can expect, unless anyone has an incite as to the perfect way to launch this truck. IE: what mode, 2 wheel drive or 4 wheel high, traction on or off. stability trac on or off, and at what RPM to brake torque it before you release. I have over 40 runs in this truck at the same location and I have gotten the times down to that they are identical on run to run. Now when I run this tank of 87 out I will run some 93 octane full tank 34 gallons and see what times I can get with it. My guess I will only see improvements on the upper speeds from 60-100 mph.
