Got my baby back today (2.6l intercooled KB, spec 2+ clutch, 3 gauge pod). Any idea what the bump is in the a/f curve?

Probably just a glitch in the a/f ratio

dude...ask the tuner...

They must have done more than one pull, does it show up on the otherdyno graphs?

That shouldn't be there. It like someone put their hand on the intake for 1 second.


Call the tuner

The tuner felt it was related to the boost-a-pump. The x-axis was rpm when I was looking at it on the screen. Not sure why it exported mph. It happened at about 4250 every run.

Looks to me like the HP/TQglitch happens before the a/f dip. I wouldnt rule it out but I would also look at other possiblities, are running manual or auto trans Ive heard of the gragh's hvaing a glitch like that due to downshift into 3rd momentarily while on the dyno somewhere. I'm no expert by any means but it seems like if it was the bap the hp/tyq glitch would coincide with the a/f dip.

Manual transmission and they checked out the bap, it seemed fine.

Anothernoob- how does she feel in the real world driving situation? Also the A/F ratio looks great regardless but the dip seems odd to say the least. Ask FordFanBoy....he knows manys things about the KB and Whipple IMO. The numbers look great and she isnt running lean so others really need to chime in on this one! Maybe fuel pump hiccup? It is the stock one right?
