Message With full bolt on breather mods the top end suffers a lot.
Here is 2 different full breather pre 96 cars, vs. a 96 full breather.
All on 91 octane pump fuel tuned to 14/15 PSI making as much power as each set up could make without knock.

Horsepower
Red Adam's 1991TT
Green Evan's 1991TT
Blue Alex's 1996TT

Notice the low end is similar, but drops off starting at 3500 RPM with a 70 to 90 HP loss on the 1996 in the high RPM.
BTW: This 96 is tuned with a early ECU.
