Street tuning with TE
I'm going to start some serious street tuning on my set up this weekend. To save time and reduce the risk of anything happen, I was wondering how much does the number in TE change the actual A/F.
For example, let's say at 4k RPM my table read 2.56 and the A/F (measured with my Zeitronix) is 13.5, how much will I have to add to 2.56 to make the AF to go down to 12.
This was just a vague example, but you get the idea. I guess the question is what is the relationship between the number in the table and the A/F.

Re:Street tuning with TE
The answer is..."it all depends"
you could say 13.5/12 = 1.125 or add ~12.5% more fuel. but i usually do that in halves.
if I calculate that I need to add 12.5% more fuel, I add 6.25% more fuel and then look at the results. Then I do it again...and again
