Hi there everyone, I'm looking for information about how to tune an 05 MR

I havnt bought a car yet, but im going to be soon, and I think the first thing I want to do is tune it. I was just wondering what there was out there for data logging, and how it worked with these cars, what programs/equipment is needed.

 

this helps A LOT:

i've been reading it quite a bit lately and I'm finally slowly starting to understand some of it after reading it top to bottom about 5 times now

 

Alright, that looks pretty good, same kinda thing like i was doing with my other car but with some extra stuff. Its awesome that the software is free, cables arent to bad, and it looks like you just program through the aldl port, (im used to obdI)

I was wondering, what kind of power gains should i expect on a stock engine with say, just a fuel pump, exhaust, and a tune?
