I made a base pass when I got the wide band up and running and found out that the AFR was 2.9ish.(7.80 @188 )

I talked to Leo Meany from Bigstuff and Precision turbo about the discrepancy between the commanded AFR and actual AFR.

They said start changing the fuel constants and fuel pressure until the numbers start to line up.

I made some changes and went 7.61 @190 (3.0ishAFR )

Pulled more fuel out and went 7.35 @195.22 3.1 -3.2 AFR

Last run of the day I never change anything and went 7.303 @195.99 the AFR was the same.

This weekend I am going to get the AFR to 3.8 or so ,then try more boost in the front half .

The correct AFR will help out the spool time and front half ET considerably.
