| the 6SP ally will last quite a while with the 300-350HP tunes but if you tear one apart after it's had those tunes run you will see the damage so evem if it doesn't feel like the tranny is slipping or damaging it is doing just that,when my i had my tranny work done i got to see first hand what a PPE does to a stock tranny.the first 3 and 4 levels of the PPE on the 6SP will last a very long time but aftet those levels your on your own.
