i suggest the superchip 3815. its been my best bang for the buck so far.i paid almost 400$ new,but you can find them used for around 200$.

 

Isnt there an SC Tuner (??) that worked awesome on the 5.9 v8?

 

yep,600$. everything i have heard its the way to go. but i donnt recomend something i havent tried.....yet. lol

thats it... I thought I saw a dyno sheet on it where it showed impressive gains on the 5.9 motor, did you see that as well? I did not find it on their site.

 

i have researched it pretty well, but have yet to see any real dyno runs. everything i have seen and heard has been off the old but dyno.

 

here it is... it is the superchips site. was thinking the #'s for the 5.9 were a typo as it is pretty high for a tuner

Yeah, everyone who has the 3815 says those numbers are a bit inflated. I think it's a good deal better than the death flash though. I am looking at one of these, as I am not into paying $600 or having a power house. I just want something to cure the death flash, so anything is better than that.

 

i think those superchip numbers are inflated too. but it is still my favorite mod.

 

even just putting in the R.R my fav mod is still the superchips, it woke my 5.9 big time
