The model year 2001 5 Hp increase on the LS1 was mainly due to the newly designed composite intake manifold and the low end torque increase from modifications to the cam shaft:

Many changes for 2001... here are some highlights:
return to 28# injectors for all models
85MM MAF with integral temp sensor (versus 74mm with separate plug for IAT)
LS1 cam profile changed to: .500/0.500, 198/208 on 115.5LSA (From:
0.472/0.479, 202/210 on 117)
All Corvettes now have the LS6 intake manifold
All Corvettes now have the LS6 engine block which includes a beefier oil pump
LS1 changes result in new output of 350 HP @ 5200 RPM and 375 Ft Lbs of torque @ 4400 RPM (MN6)
Pup cats added to all models
Stronger synchros in all transmissions
Exhaust manifolds revised (5hp regained) - thin wall cast replacing SS
manifolds
Torque Tube changed from metal-matrix composite to aluminum alloy 6061, increased in dia from 55 to 63 mm.
Driveshaft couplings have also been upgraded on manual-equipped models for additional strength and durability
Indeed, it was a good year!!
