if i have hks downpipe, hks intake, hks xhaust, ralliart ground wires(they said my ground wires usually push 5-10more hp once installed) how much hp do i gain over stock. just give me a rough estimate

 

If you aren't tuned for you mods, I wouldn't expect a whole lot. I have the same mods as you + a MBC @22psi, BOV, custom flash, highflow cat, and IC pipes. I am hoping to put down 300whp on a dynojet. On a mustang maybe 260 or so.

 

if you haven't been re-tuned or reflashed, you're probably lucky if you're breaking even, maybe +5 above stock.

 

Little bit difficult to mod the power of an Evo without a reflash

 

LOL he's definitely gaining more than breaking even with just the turboback, but i would say maybe 10 over stock. exhaust definitely helps even without a tune

 

i have never heard of ground wires adding horsepower

is the 5-10hp what ralliart states, is that so they can sell it for so much?
