Anyone running the stack? What do you think? I am running this stack, what upgrades should I look at next to complement the stack?

i think your wasting your time and money.... sorry to put it so harshly but you could be hurting your engine by stacking tuners together, i HIGHLY recommend that you stop running a stack.....

A PPE hot +2, or EFI live will make your truck run 10X better, plus i personally dislike bullydog products...

if i were you i would also be looking at transmission upgrades of a Tq-converter, clutches, and shift kit, otherwise your tranny will take a dump at over 100hp above stock

please stop stacking on your duramax!!! your not doing it any good:thumbsup

I have the PPE boost valve, Cold Air Intake, 6in Stack. I have no fuel work. I was looking at getting the PPE Common Rail Ported Fuel Fitting but not sure on that yet.

i still recommend for you to get rid of your stack, your more than likely making way too much injection timing, your going to hurt your Injectors, and they aren't known for being able to take much abuse.....

im telling you that your playing with fire bud

If he wants to run stacked tuners that's his option. Transmission upgrades are probably number one on your list, a lift pump, maybe duel CP3's and bigger injectors to take your stacked tuners.

stacked

Yea dumb A:haha:haha I think these guys are right. Take the bully dog off and get that latest software for the quadzillia, you can sell the chip and put the money towards other things.

Save your money and build the trans first, then buy EFILive from a reputable dealer...most offer tunes with the purchase.

Larger injectors would allow you to run less pulse width and timing to get the same power, so thats a thought.

Dual CP3s are a waste on a stock motor/turbo truck, IMO. No point to it. Single will handle 600+rwhp.
