LFA=10.7:1 AFM VVT 332 hp 367 lb-ft
LS2 =10.9:1 400HP 400 lb-ft
Horsepower (hp @ rpm):
LFA Hybrid 332 @ 5100*
LS2 400 @ 6000
L76 367 @ 5400
Torque (lb-ft @ rpm):
LFA Hybrid 367 @ 4100*
LS2 400 @ 4400
L76 375 @ 4400
we could assume the TRUE specs of the LFA is 375 HP and 390 lb-ft at the L76 rpm speeds just for the ICE..
it's obviously they watered down the TRUE numbers.\ because they line up slightly better to L76 numbers at the same rpm (because of the slightly higher compression ratio)

The biggest difference in power is due to tuning and camshaft. The numbers aren't watered down.
To the OP, I would suggest taking the tires to 40psig, we saw a measured difference going from 35 to 40. What year do you have? You might be able to get a Tahoe hybrid front air dam to fit and you would have a factory look.
Nvm, I see you have an '08, the air dam should fit if you can find one.
