I read an article recently from nelson performance that claimed to add 100 proven rwhp to a silverado 5.3 with the following mods:
pacesetter headers
stage II cam package
custom tune
fm 40 muffler
The article: http://www.ls1truck.com/forums/front-page-news/12377-silverado-100-horsepower-performance-gain-budget.html
I'm starting with a 6.0L rated at 366 horses (according to the general) at the flywheel. So can I assume 285 horses at the wheel? I want to add as much hp and torque as possibe without maxing out my credit cards. I was planning on the following mods:
pacesetter long tubes
stage II cam package from nelson
custon tune from nelson
flowmaster 40 muffler (thinking 2.5" piping?)
gmp air intake or aem brute force or fram boost??
NO tbi spacer (since many think its a waste of $$$)
maybe a ported and polished throttle body.
WHAT HP CAN I EXPECT TO PICK UP? I want to get to 425 at the rear wheels or am I crazy? I used to have a 93 2-door yukon that I carbuerated with headers/cam/exhaust that made just under 450.
WHAT ELSE CAN I ADD? Bear in mind that this will not happen until January or February so I have time to change my mind. It is going on an 08 lifted 4x4.
If I want to go FI later (very unlikey) what would I have to change? I'm assuming the exhaust and the tune.
