hi

with the mod chips that change the air/fuel do they save fuel? are the magnas more powerful with them? do they damage anything?

what wires and what sensors do they normally go in

sounds like you need to be a little more specific... remember that mitsubishi has spent in excess of millions of dollars to perfect the running state of their cars, that being said however it really would depend on the type of magna as to whether or not performance tuning can be accomplished with a chip

I wouldn't touch any of those performance chips , every engine is different thus every engine should be tuned specificlly to its needs and modifications...just in opinion

Man there was a huge thread on this a week ago. Search "unichip"
