Boost stick + Stock tune = Crappy MPG?

[SgtKilroy]

I'm sure this is going to make someone very amused, so please pardon my ignorance. Still learning. I got my boost stick from KD and put it in and my mileage seems to have dropped a bit. I'm still on the stock tune until Diablosport finally sends my tuner back. I'm making 30+/- lbs of boost now but if it makes my mileage go down I may take it back off. My impression was more boost=more efficient combustion=better MPG. Is this incorrect? I sure do love the sound of the turbo with it on though...

Well having the veins open more while cruising usually yeilds better mileage that and a combination of more timing. The boost stick will close the veins more at cruising than the stock tune, which equals more restriction less, mpg.

More boost does not (Usually) equate to better mileage..

Gotcha. Thanks. I wish more and more every day that I'd gotten EFI live and done this right. :banghead:

Just out of curiosity, when would more boost make better mileage?

 

[03dmaxin]

when your barreling out soot and jus waisting unburnt diesel so when that occors then turn up the turb.psi and burns more efficient which = +mpg instead of -

 

[SgtKilroy]

Makes sense. Learn something new every day. Thanks yall!

Ya once you go EFI Live the boost stick comes out anyways...

 

[SgtKilroy]

If only I could sell the AODE trans, predator tuner, and the tool box off my truck, I would have enough money get EFI Live. I doubt it, but yall know anyone that wants to buy any of that?

James, out of curiosity, what were you trying to accomplish with it?

 

[SgtKilroy]

With the truck? Not much. It's my daily driver. I just want to put enough power in it to shut the ricers up every once in a while. The boost stick was to go with my Predator that I still haven't gotten back. (I'm never ordering anything from Diablosport again.)

when I tried the boost stick with a predator, my mileage went down too. Depending on which version of code is on the predator, you may not actually need the boost stick. It was meant more for version 2, V2.02 and up had more boost added to their tunes.
