I have been doing a lot of reading and have gone threw a few different chips/programmers my self. Still haven't found one i like so i was wondering what is the hands down best programmer/chip or stack for a 2003 Cummins. Mine is a cali 235hp motor. All opinions are appreciated. Thanks

For 03-04, especially with the 235 motor (like mine), smarty hands down.

You will get a lot of opinions. I have a friend that has his 03 stacked with Banks and BDTD.....it flies. I like the Smarty......easy to use and a lot of power.

Happy with my Smarty

I would like to try would be the PPE.

I know the PPE works very well on the Duramax.

I would also stack with the TS.

I would be interested to see what the Adrenaline does too.

Used to hear a lot of good things about the TST too.

my 04 is very close to a 03 cept for the detuned 235 engine and the diablo pred is a good chioce for the 03-04 truks,but if i were to do it agaun i would get a smarty,not becasue its any beter or worse than the pred but it does tiresize which the pred doesnt and i think the smarty will have more tunes and options available than the pred,just my opinion

Well on the 03-04 trucks i really think the smarty is the best, with ppe right behind it, but on the 04.5-07 there are some other really good ones

x2 The Smarty catches us back up to where we should be and then some.

The Adrenaline/Smarty combo is very NICE. Until I get my hands on a PPE Hot+2, I would have to say a Smarty and a pressure box will get you as much power out of an 03 as you would want. I would not run out and buy a Smarty POD right now as you wont be able to load the beta tunes(which seem to run the best on 03s), i would just get the regular S-06.
