I've got an 02 Z71 Avalanche with the LM7 5.3L and came here to read up on how to get some power out of it. I run the truck out on the sand dunes and would like to get a bit more power for being on the sand. As of now the truck sits like so:
GMPP CAI
3" Flowmaster 40 series catback
HyperTech 91Oct tune
stock keys cranked for my 285/70/17 Nitto Dune Grapplers

This month the truck will be getting:
Pacesetter LT's and ORY
2500 stall and Trans-Go shift kit
Snow Performance GM MAF methanol injection kit

After those are done I will then take the truck to Livernois Motorsports for cam, springs, push rods, and dyno tune. I have lots to learn here and plan on doing more research to find out what cam will be best for my setup.

 

Welcome to the forums!

 

Welcome to the forum neighbor!

 

welcome from a fellow MI duner.

i'm not sure what you would need the meth for if your not running any power adders.

 

Livernois parts are good, their labor is not cheap. Aside from the tuning you should DIY!

 

Welcome from the East side!

 

Welcome over!

 

The GM meth kit is for N/A motors and it used to lower IAT's that way you have cool air entering the motor and helping out on the performance a bit.

 

Welcome! love the sand dunes.

 

ya i know what it does. there is a better way to spend $300+ on a n/a motor. put that money towards your cam/spring/pushrod swap. there is not point trying to cool air that is already cool. now if you had FI i would say ya because as you compress air it heats up.
