[GORILLA]

i know for the 05 4.7 V8 VVTI they have these,
now maybe more?
if they had a truck to help map another intake, they would do it.
but when i bought mine a few months ago there were these intakes available for the 2005 4.7 VVTI :
stock box w/stock filter
stock box with a drop in aftermarket filter example K & N or true flow
and
volant cai
that was it at that time.
maybe now they might have added some other intakes.
but all headers
and
all cat back mapping are exactly the same. only 1 map for each.
that's why i switched from K&N cai, to VOLANT cai.
hope it helps,
