Hi all!
I'm looking at doing some modifications to my '03 AV Z66 5.3l to, hopefully, increase gas mileage. Does anyone know if this stuff works? Here's what I'm looking at.
Airmax intake: http://wheelskin.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=W&Product_Code=SPE-15300
Helix Power Tower Plus TBS: http://wheelskin.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=W&Product_Code=SPE-53015
Proflash programmer: http://wheelskin.com/Merchant2/merchant.mv?Screen=PROD&Store_Code=W&Product_Code=SPE-200325
And I will probably eventually add the flowmaster exhaust.
Is this overkill? Will it increase gas mileage? If so, does anyone here have any experience with this equipment to say approximately how much of an increase I can expect. I'm mostly interested in the gas mileage over the increase in hp.
One more question! Does doing these mods void the warranty on the truck?
Thanks in advance for any help!
