Need more HP on my 2009 Silverado 5.3

Need more HP on my 2009 Silverado 5.3

Postby Ranchero64 [OP] » May 10 2015, 8:01pm

I've got a few questions, I've had a few upgrades lately, and love the power but need just need a bit more, here's what I've got so far-

3" FagaFlow cat back
Airaid MIT
KN
Lewtune

I'm not looking to go as far as a cam or anything major etc...just a bit more. (Hp like crack I NEED more)

Another note-
Also, every once and while, when the truck starts, I get some major lifer tap for about 5 seconds. Then it's gone, I know it's kinda normal but wow....I run Mobil 1 with some Lucas additive, not really sure if that actually helps, It Used to be worse before the Mobil 1 changeover.


Also what catch can have you guys found works best ?

The truck has 57k on it when I got it 2 months ago, I always assume no maintenance has been done when I buy a car and do some basics, is there anything that should be done that should have been done, other than what's in he manual ? Little stuff that needs to be cleaned or replaced?

Also a tune question- I drove my wife's 2009 Tahoe the other day, first time in a long time, it's very nice to feel how SLOW it is compared to the truck now that my Silverado has a Lew tune. The Tahoe shifts so much smoother than the truck ever did . Are the factory tunes (ecm and tcm) different from Tahoe to Silverado? Same year same engine codes.

I'm a old F**d guy in the middle of a conversion to wearing a bow tie , and fuel injection is all Greek to me, and need a bit of guidance.


Thanks for your wisdom.

At best you added 15 hp with those mods, as suggested long tubes or go big or go home and invest in forced induction, turbo, procharger or supercharger.

I know I didnt get mass amounts of power and I'm not looking to get 100 more. Maybe spending 3-500 more at the most.

Any thoughts on the ticking and catch can?

As for the ticking....and I'm sure I'm going to get heckled for this..... try a seafoam treatment(as per their instructions) then do an oil change.
