Not sure what you are asking.... do you mean the A/F enrichment for cold start?

 

Well, my dyno showed pretty good A/F at 13.1 and started to go up once it hit 5k rpm's. So I was told to add some fuel and it would keep it where it should be. I was just wondering if anyone had to add fuel maybe for other reasons in why did they have to do so.

You need to provide the dyno data to pcmforless, and let him make the required corrections in the program. That's the whole purpose of the "tune". How lean did it go? Are you sure you have a healthy fuel sytem, and the correct injectors? Was all this info given to pcmforless for the initial tune?

 

No, the initial tune was done before the dyno. after the dyon, I faxed pcmforless a copy and that what he told me he needed to do to it "add fuel"....

It is way lean, throwing 2 codes "44 and 64" Blm's are maxed out also... as a matter of fact, I think I sent you a copy of my log, remember? I still have the stock injectors on the car though.
