Box for early 04?

[DocDetonancour]

Does anyone have a late release that increases mpg? Seems there may not be enough market for the 03/04 that hasn't already been taped? The Predator is still advertising 100 day free trail and 100 miles per tank in the latest issue of "snowest" mag. Doc

i am not sure exactly what you are looking for doc,

however i run the TST box 99% of the time on 2/2. in summer i was averaging 20. 2 mpg. higher in town (21+) and lower when over 65 (19-).



for winter now i am around 17-19, which includes at least 1 min of idle during start up.



i am not sure what it would be without the box. i have never shut it off and have had it on the truck from almost new. the truck was around 17 when new.



all these mileages are calculated per tank, with periodic looks at the overhead. they agree as long as i keep my foot out of it. the overhead is way too optimistic when i run it hard.



hope this helps
