i had an ATP replacement actuator in my car that gave up after 20K miles.... up until it started leaking, it held great boost, a steady 7 psi. Once i got the forge in as a replacement, on stock settings i will only hit 5 psi, and it won't hold that till redline, the boost decreases as the rpms increase. Even with a boost controller on, it will spike to about 8 psi, and then taper down even more quickly to end up at below 5 psi by the time i get anywhere near redline. I worked with forge a good bit trying to fix the problem and never came up with a solution. I personally would rather go with the ATP actuator knowing that i'll have to replace it sooner.
