Is there a general rule of thumb for variations in boost VS A/F with the kenne bell? In other words, just as an example if you had a flat A/F of 11:1 at 15psi, how much would the A/F be affected by going to 17psi? Also, is anyone running 21psi on pump gas?

I know when I was stock the A/F went off the chart with the eaton and when I had the KB on with no chip the A/F curve looked the same but was just higher, safe but higher. Even though it was only 1 psi increase it raised A/F quite a bit, hard to tell for certain since stock it dropped off bottom of graph and its not a very accurate comparison cause I gained 72hp.

I know with the eaton 4 more pounds leans it out about half a point... not sure on the kenne bell... Either way i would get the A/F checked somehow.

hope this helps a little..
