Upgrade Master Achievement
Upgrade all Cop Pursuit Tech in one car to maximum level and equip both slots
You can obtain this using your very first car in the cop career, the Mercedes-Benz C 63 AMG. You will have four pursuit techs available to you, each with only 1 rank, it will take 65,000 SP to purchase all of the upgrades. Head out onto the streets and do a couple events, bust some racers, whatever you want to earn the required SP, but DO NOT complete the assignment. Doing so will mean unlocking more tech upgrades meaning more SP will be required. Once you have your 65k head back to a command post and purchase all four of the techs, equip two items in your slots and the achievement should pop. You can also get this with zero effort if you wait until the rank 10 mission that has you going undercover in the Ferrari Enzo, this car has two rank 4 techs available, you just have to unequip them and equip them again for the achievement to pop.
Now although both these methods are confirmed to work as of right now I am not sure this is how it was intended to work, it reads like the original goal was to unlock all 6 pursuit techs and upgrade them to maximum level. In the interest of providing as much information as possible, and in case the above method is patched, I will also provide the information needed to obtain all pursuit tech.
You won’t unlock all 6 pursuit techs and their maximum upgrades until rank 15, at this point you will have all 6 techs and each one will have 4 levels. To upgrade all 6 will take 1,160,000 SP. It’s honestly not that hard to earn that by this point, the fastest method I found to earn that much SP is to find a [Medium] hot pursuit and just keep doing it over and over for about 20 minutes. Go back to a command post, upgrade your tech and equip 2 to unlock the achievement.
