Like it says, I need some advice to wake up my 5.3L. She's been one hell of a truck, the best vehicle I've ever owned! She's got 115k miles and has had no problems and runs very strong. I only use the best parts on her and keep V-Power 93 octane in her. I have only got a couple of mods so far... Airaid intake w/ MIT tube, Flowmaster muffler turned down, NGK TR-55s, MSD 8.5 mm wires, and 180* t-stat.

I am very soon going to get a Hotchkis TVS kit. I plan on getting: Nelson or MTI 93 Tune, AS&M LTs, Eaton posi, 4.10 Richmond gears, Magnaflow cats and muffler, and a 2400 stall. I eventually want to do a LQ9/4L65E swap and get a STS turbo.

What mods should I do next to really wake her up. I would like do to a full tune, but don't want to wear the tranny out too fast. She's my daily driver and has to stay dependable for now.

 

do really want to jazz up the 5.3 or do it all to the LQ9 and just swap them out?

 

6.0 is the way to go dollar for dollar there is no way to beat it. If your gonna stay with the 5.3 I would do gears and a posi to begin with.

 

yes it helps

 

element you cant let me be faster than you for 3 days, i was just starting to feal good about it but no you have to go and try to pass me

 

I would like to some mods that can be re-used on the LQ9 when I get it. Like headers, ported and polished TB, etc.

I guess for now, I'll do gears, exhaust, and maybe a stall.

 

then get you a set of pacesetters,posi,4.10 gears,then get you your turbo and then all what you have will fit on a lq9/lq4 or even if you want to a 408 423 427 what ever the hell you want.

 

What are you talkin' bout ? Who said anything about being fast? My truck is sloooooow! I get passed by old people who all they do is this Don't worry, it won't be long before all you see of me is

 

Just what I was thinkin' of doing.
