OK, I've sifted through for an hour trying to find more info on the DiabloSport...
I haven't found anything apart from most people here taking it that its second nature to know what these things do.

I'm stuck here in Germany being a Brit not know an awful lot about my truck and hearing you chaps go on about the DS has got me interested.

As far as I know:

You can Re-Program to sport, tow, eco, extreme......

How much better MPG do you get from the eco mode?
How much better BHP do you get from extreme mode?

Also what are the benefits of a trinity.

BTW next week I'll be picking her up (5.7 ST 4X2 with lots of extras) 3.92 (I think)

 

Also is the Diablo the best one to go for?

 

i believe a lot of the guys have been going with superchips, they have a pretty good rep with tuning.

 

To anyswer yor Diablo question the only benefit the trinity give you is

1. Warranty on your drive train for 2 years from Diablo... Note if you get the tranny add on tuning the warranty is VOID.
2. A fancy screen.

I had a Diablo and dumped it for SC. I had the Diablo when it first went to market and it had some issues. Once SC came out I switched and have not had an issue.

As for the SC, it is a big difference (so was the Diablo). I FINALLY have a custom shift schedule I can use and love. I am back to making my NEW tires yell from 25ish or less, stock tune my new tires would just grip. I will post the settings at some point.

MPG, not much. It would take you MANY miles to make up for the cost of the tuner.

 

That would be great if you could post the shift schedule you are using. I gave up playing around, took too long and I have not had the time since. The posted ones were too aggressive for my daily driver here.. thanks !
