three stage "chip"

[not_high_enough]

:bowtie: :bowtie: I saw a shift somewhat of a chip in a summit catalog for the 95 TBI 350's that is a three position switch, (stock, performance, and towing) anybody know anything about these? :bowtie:

Basically is increases the line pressure on the 4L60e on those different settings. I don't recommend the line pressure alone...you'll break something. I recommend either billet servo, shift kit, or both.
