Has anyone seen an actual increase in mileage by improving the airflow, whether by a BHAF or other system? If so, how much? I currently have the VA3.2 and don't need more power but rather better mileage.

 

An air system by itself will probably not yield a mileage increase. You probably will also need at least 1. a free flowing exhaust and possibly 2. a pressure or timing/duration box to see any mileage increase. An easy way to increase mileage without these is to add some PS and MMO to your tank at each fill up. The ratio of about 3:1.. Also slow down. 75mph down to 65mph on the freeway will cause mileage to jump a lot!!!!!

 

PS - Power Service, MMO - ???

Combined driving my last tank was 20.04. Highway driving my speeds are under 70. Is there a timing box available that does not do pressure?

When I switched to my scotty 2 my truck was stock and I saw about 1 mpg increase overall. After I installed the exhaust I saw another 1 mpg.

 

There is a police officer up here with a 96 Ram and he said he is getting 1.8 mpg improvement from stock. He is very technical and meticulous with his records and showed me. He has since sold over a dozen to other Ram owners in his circle.

Recently I have gotten a few reports from the Scotty 3 as well.

Perhaps they are seeing this because of being lighter on the go pedal due to the fuel prices? Today I netted 18 mpg city on the overhead. Filled up and calculated it to be 17.2. Best city mpg ever for me. I am also using Milligan Biotech biodiesel additive.
