STILLEN QR-PRO or Greedy E-manage Ultimate?

[Lazyron007]

Which one is better and would provide more hp on a 2003 2.5S?

i have the qr-pro and it gave me quite a bit of power. not sure how much but it was definately a huge change.

how hard and how long was it to install? did you do it youself?

i got the stillen qr pro.. and i heard theres no difference between stillen and greedy. except prices.. stillen is about 450 and greedy is 560 so about 100 diff.

as for the hook up you would think it would be an easy job but looking at all the wires i just took it in to a car audio shop and got that intalled with my fog lights. cost me 120$...im sure you can hook it up yourself if you know where everythings at.

this is the link for intallation for the stillen, so see for your self.

Since there is the option to turn the QR-Pro on an off, when you turn it off can you put unleaded back into the car?
