My truck go's in for the tranny as soon as i get my TC, and i was going to buy EFILive the same day. Now i'm wondering if i'm just setting myself up for disaster? the old girl has 170k on it, and i'm wondering if i build this tranny and throw a nasty EFILive McRat tune on it, am i just gonna burn the truck down in a week?

the banks dynoed in around 425 rwhp and i'm wondering if the bump up to 500 or so, is just gonna pop it. I know EFILive is great for makeing power, but is it also hard on all components?

Is 170k just to many miles to put a EFILive tune on? How many miles do you have?

ok no one's gonna touch that. i'm gonna get it, and just not run that nasty of a tune. just enough to keep me happy. Still alitttle curious as to how many miles everyone has?

The only guarantee with turning your truck up, regardless of HP increase is that the engine life will decrease.

So far, the general reliability of 500hp class tunes is pretty good, mostly charger failures when failure occurs. Bad injectors seem to be claiming more engines than tuning has.

About 70k on Blue and runs like a clock, and it's had a hard life.

There are only so many horsepower hours an engine before it gives up. That said I would say at 170K and 500HP you are on borrowed time.
Im not saying it would blow up right away, but would be happy spending all that money on a transmission and efi live only to have it blow up at 175K? 180K? 190K? 500HP is a big risk on stock internals period. Just cuz people are getting away with it doesnt mean its safe. But 500HP sure is fun to drive.:D

no no no, you guys are supose to tell me that i will be fine. especially you McRatt :D I've know the truck for it whole life, and it was babied untill i bought it ;)

I'm not worried about injectors or head gaskets. It's the full rebuild with machine work that i'm afraid of.

You'll be fine...

Oh im sorry.:p:
Yeah it will last forever, especially if you strap on a HUGE charger, and maybe dual CP3s.;)

I think a DSP5 switch is a great idea, only use the big tunes when you need them, in theory this should prolong engine life.

SHOULD..... haha, keep it on the highest setting....:D
