Gets the speed based shift points back closer to stock.
I run 45 to 50 psi in mine on the stock TRD 18's, they're not domed and showing no obscure wear after 31,000 miles. In fact, these tires look like they're going to last me somewhere around 70k. Rides like a truck, you feel the bumps at this psi...I like 45 psi better, but they are at 50 right now cause I haven't lowered the pressure since my last tow and week or so ago.
87 octane is all I run, most of the time from the Safeway Grocery Store Station.
