Does anyone know why at WOT the AFR is being commanded to as low as 10.3:1 when the lowest the PE table is commanding is 12.5:1?

Might consider posting your .hpt file if you want a response.
It doesn't have to be perfect, it just needs to be done in two weeks...

OK, here it is, it pretty much a stock Stage2 tune.
Cat over temp.

You can tell that from the tune file? Or should I say what value should it be?
Clogged cat. I cant see your logs, what kind of boost are you seeing?
Its either that or the IVT gain table under OL & CL both are commanding afr's in the mid 10's so I would start thereOriginally Posted by Rush

Looking at some old log files from WOT runs, I'm seeing temps over 1900F, which exceeds all the Cat temp thresholds. From what I understand when the AFR drops below 11 or so you start to loose HP, so this may also explain my lack of performance on the dyno.
So what can be done?
As far as boost goes, at my elevation I can hardly hit 15PSI.
shut off cot and piston protection. rework the maf and pe table.
Something else must be adding fuel at PE, I disabled (set the values way high) piston protection and COT, and made a few WOT runs this morning and the commanded AFR is still less than what the PE table shows (12.5:1) at the lowest point; unless I'm reading it wrong.
I seeing commanded AFRs in the upper 11s when 12.5 should be the lowest.
