Best N63 tune out there, doing 8.1 60-130 with meth and Stage 3. Best of all is the customer service, Sergey always replies and helps with my car past the tune.
So besides the obvious, keeping my oil temps down around 5-10 degrees, the most noticeable thing after installing this oil cooler valve is not having to add a quart of oil to my engine every 2-3 weeks like I did before installing it ! Just in the extra quarts of oil that I don't have to buy anymore , it paid for itself in no time ...
