Okay I have seen this only a few times and wanted to see if anybody else had also seen it also.
The car runs normal and spark is fine but go WOT and the SPARK goes to 0 or bounces around 1-2 degrees and is dead in the water.
Any Ideas Guys?
WOT and ZERO Spark

Here is the tune.
Nothing Special at all
Car idles, drives normal. Everything looks fine.
Wish I had a log but did not save it.
Go WOT and 0 if I go into the minimum table and put like 25 in it runs fine.
Any help would be great.

Edit, compare your tune to a stock tune and you will see a few things to address.
