I'm considering it over the winter for my MR20 as well

Good luck,bro... i will waiting for the report..:thumb2:

i'm not sure this has been done before, but i think i've read that the versa ecu is adaptive. meaning it may take a little while for the car to figure out what you did to it. then you should see the improvements.

yap, you're right bro, the ecu is adaptive.. i had tried...:thumb2:
