track time's tuned vs un tuned
 

hey guys what is the average et redution from geting a tune?
i had a full tune done and had 90% of the tq management tooken out and my car was realy rich. my a/f ratio would be fine till about 4k rpm then would go realy rich. im shure it was killing higher rpm power. what have you guys experianced? i have read on here that just takeing out the tq management mad a good diff. what was your results?
thanks guys.
