Ram 5.7 hemi I was first off wondering what generation my truck is and what I should do performance wise to get the best horsepower gain for my dollar???

 

1) 4th Generation
2) 390 is plenty

 

I've enjoyed the SuperChips tuner. Makes a very noticeable difference on 91 octane tune. I believe it bumps output to something like 415 (might be wrong). Always makes me appreciate it when I return to stock map if I have to bring it back to the dealer. Fortunately that isn't often.
