18HP with ZO6 MAF??
Not unless their is a serious tuning issue, the MAF accidently corrects. 5-8rwhp is realistic if the car responds to a different MAF.
SLP 85mm MAF = 6rwhp on my car. Descreening the stock one would probably do about as well.
Did the 02 cars have the LS6 MAF?
Bellows 1-3rwhp, I really doubt that on bolt on car.

I gain 1.5 mph after changing to the Pace LS-6 vv MAF.
Also 5 of my friend have this same MAF and have gain close to the same as my car.
