There is no such thing as "Learn Down". The tune works by setting a target calculated TQ and then making adjustments to acheive that calculated TQ. If you produce "more" than the set calculated TQ then the car will adjust spark, fueling, etc. until you match the target calculated TQ. Even GMS1 works in this same way, the calculated TQ setting is just set higher.

The GMS1 tune has more built in checks for TQ, abuse, etc than the stock tune. These are the referred to "nannies". Using the stock tune with the 3 BAR MAP sensors you can see better results with your tunes.

It is a good idea to listen to advice given by Iam Broke. He knows more about tuning the LNF then 99% of the people on this site.
