Hello everyone,
I wanted to start a thread on engine mods. I searched the site using the most common of terms and did not find anything. Maybe, I used the wrong terms and there are tons of posts, but I haven't found any.
My interest is due to my trying a mod using a JDM ProM chip on my vehicle.
I am just adding this mod, and realize it could turn out to be a flop. The numbers at the pump combined with OTR experiences will be my determining factors.
My vehicle:
2012 Nissan NV HD 2500 Hightop
4.0L V6, 261HP
Nissan 5 Speed Automatic Transmission, same as the V8
GVWR 9100, GVW ~6450, Loads ~1000lbs
My average loads are 1200lbs or less. It's the freight business, the loads are rarely the same....
K&N Highflow Drop in air filter - Refreshed/Cleaned every 25K
Mid-Grade 89 octane gasoline .. only!
Starting mpg's around (15-17)
First mod added at 10K: K&N Filter MPG increased over time to (17-19+)
Second Mod added at 48K: JDM-ProM chip
I won't spend the money on a dyno (I'll use the Butt dyno for now), unless I see some extreme changes in the performance. There are too many factors that influence our mpg's and engine performance with everything from lead foot syndrome to tail winds that can muddy up the waters as far as results go. I'll report what I know and calculate based on feather foot driving. If it is good, then I'll say so. If it flops, then that is what I will say, as well.
Respectfully,
Mark
