Envoy/ XL / XUV Modifications

[Chronic]

Anyone care to share pics of any cool mods done to your vehicle? I'm looking for ideas on how to pep up my '04 Envoy XUV V8? ie intake, chip, etc. So far I've changed the air filter to a K & N and modified the exhaust fron a single y'd into dual

 

Thanks,

Andrew

I believe Nelson has a PCM upgrade for the 5.3 V8. Nothing yet for the 4.2 I-6 yet. From what I have read on other forums, best to stay away from Jet and Hyperteck products.

Had posted this info for someone earlier.

 

For my 2003 Envoy XL SLT V8 I'm using a Diablo Predator, True Flow Intake, and Granitelli MAF

 

Predator is P/N# U7195

True Flow is P/N# 10505

GMS MAF was off my last 2000 GMC Sierra (same model as any GM LS1 Truck)
