budget minded performance mods
hello all im pretty new to the site,as you can tell by my posts. built a few street rods and a 74 blazer with a stroker and some sqeeze, for the sand dunes and mud bogs. my question is being new to the computer controlled world of performance, what are some inexpensive easy mods i can do for my z/28 that i purchased about a month ago? already have magnaflow catback ,k&n filter,and hypertech programer,car was bone stock when i bought it. any tips would be appreciated, thanks.
