My bro has a 04 5.3L silverado Z71- and he wants to some more power out of it his plans are-

JET chip stage 2
JET thermostat
K&N air filter
Nelson ECU (WILL THIS KEEP WARRANTY?)
Long tube headers (please recommend a company)
no cat w/ 2.5" exhaust and 40 series
Underdrive pullies (please recommend a company)
Grantelli MAF
MSD coil packs

Do you guys think he should do anything different like e-fans or something else or use different bolt ons? he just wants to make it a bit quicker he plans on turboing it later on like 2 years from now....

 

Just scratch all that stuff and get a Tubo or Magnacharger (Radix) from the get go. I know it cost more up front but its cheaper in the long run did I say RUN yea I did thats what youre bros truck will do if he does this.

 

Longtubes- ASM's
CAI- K&N Gen II
Tune- Nelson Performance
Pulleys- ASP
160o Thermostat
Exaust- no cats, 2.5 pipe, Hooker's Aerochambers
Stall- Fuddle 2600 (Trans-go Shift kit)
4:10 Gears

Those are the mods your bro needs to do to bring his truck to life, forget that Jet Chip.

 

what he said ^. your wasting money on alot of that stuff. most of it does nothing for you. these are the best mods for the money if you dont want to put a blower on it.
cam
long tubes
tune
gears
converter

 

warranty....... or can he run the s/c and still keep the warranty?

 

im pretty sure a blower will not void his warranty. also if he buys a radix im pretty sure they offer a powertrain warranty also

 

what does he need to upgrade for the supercharger- he told me he wants to upgrade everything that will help the s/c out b4 he actually get it- so what should he do-

MSD coil packs
Injectors
Fuel pump
long tubes
2.5" exhaust
CAM (he said hes gonna go big or go home when it comes to the cam)
Heads- maybe port/polish, teflon seals, 1.6 rollers, valve springs, valves?
nelson tune

 

where can i find the ASM headers?

 

injectors will come with the radix. dont worry about coil packs you dont need them. fuel pump comes with radix. get a set of pacesetter coated long tubes. 3'' exhaust with magnaflow mufflers. get a lingenfelter GT2-3 cam i believe thats the correct one. im not sure on which heads to get. as for the tune i will be tuning before to long unless your in texas and you want a dyno tune from allen

 

ASM"s Headers fit 4x4's I got my threw Speed & Engineering they are a sponsor here. I would recommend Pacesetter's but I didnt think they fit 4x4's.
Hey Fogle do you have a dyno down there in Waycross or are you just tuning with the labtop.
