I only own a mk4 before my current mk7 and I kind of left the VW world between the 2, so I'm no expert.
From my perception, APR and Uni seem to have had fairly comparable numbers on previous generations. But it looks like there's a noticeable gap in low end torque on the mk7 platform.
I definitely like UniConnect, but APR seems to win the numbers war here. Uni mk7 tunes are often referred to as conservative. I don't do 1/4 mile drag and I don't track my car, so does that torque difference really make a difference in every day driving? I don't know.
