Change the spark plugs and see if that helps. When replacing plugs put some never-seize on threads as these plugs have been known to break off when removing them, then you have bigger problems.

check and see your boost level. The stock gauge only goes to 70 mph and if you did 75 mph on gps you would need alot of mods. Low boost could be caused by loose sc belt.

Dash dreamometer (must be!) or GPS?
