I am going to be buying a JLT CAI and a Tbody and Plenum sometime this week. I will shortly after that, buy a midpipe of some kind to go with my LM1's. What do you think I should do after that? Other than gears, those will come a little later and I have my reasons for that.

 

i would say pulleys they relatively cheap $200 and are good for about3-5hp

 

Definitely get the tuner. Your getting to the point where it's more than worthwhile.

 

What kinda gains would a tuner be good for with those mods?

 

yeah pullies are the cheapest might as well do those first.
