[Newell Attack]

Hi Guy's,

Question.... After having a new Jake Brake installed I have seen a decrease of mileage (hand calculated of course) with new jake my averages are 5.8 to 6.2. Prior to new jake I was averageing 6.5 to 7.5 Does my newly installed Jake brake effect my fuel mileage?

I do notice that when the Jake is engaged, there will be a bit of unburned fuel coming from the exhaust that

I can only see at night time when there are headlights shinning from behind.

Thanks in advance,

Newell Attack
