I just installed the bully dog gt tuner on my van, and i can't keep my foot off the throttle. :eek:

Amazing what a tuner can do.

Haha, yes you will blow your trans and fast if you keep punching it. But I guess that will give you good reason to rebuild it stronger!

Keep an eye on your tranny temps and you will be fine as long as you do not something stupid. I have 150,000+ miles running a tune and my original trans is still good.

My van just hit 220,000 miles. Been running Bully Dog for last 40,000 miles. Other than shift kit the trans is all stock. I like to blow black smoke!!!!

what setting do you normally drive in? bully rep told me performance mode provides best fuel economy. true?

do you tow at all? if i tow something heavy, am i better off in tow mode or stock mode?

also, what shift kit you got?

They have had them for years. The vans just never got a dash gauge until I think it was 2008 or newer.

Tow in tow setting. I use my small tune for everything and the big tune for play.

I have left mine on performance tune. Towing or not. Extreme once and while when there is a need for a nice Cloudy Haze of Black Smoke!
