Right now my 00' 5.3 Sierra is completely stock. I am thinking of adding a CIA, Cat Back, electric fan, and a custom 93 octane performance tune.

If the stock setup yields 285 HP and 325 lb-ft at the flywheel, what could I expect at the flywheel with these mods?

Does 325 HP and 375 lb-ft at the flywheel sound realistic with this combo?


Thanks in advance,
Dave

Actually, I am planning on getting a nelson tune.

BTW, anyone have an estimate on MPG increase with this combo?
