I can make 3.3 pulleys to run with stock maf/injectors/pump if someone really wanted to, but when you spend over 3k to get to mid 500s, most guys don't mind spending another 1k to get 600+.
On a stock car, to run the 2.6-3.2 pulley you need injectors, fuel pump booster, and maf. We have a package with 60s, VMP fuel pump booster, and VMP3000 maf for $799.
