Would I benefit from a custom prom?
I have a very mild budget build in my Iroc currently running off the stock 305 auto chip, it's a 4 bolt 1 piece rms truck block with world products s/r torquers, a 96 y-body lt1 cam, home ported factory tpi setup with a bbk AFPR set to 45 psi w/o vaccum and 22lb injectors (and an airfoil that was installed in the tb when I got the car 
) Compression is about 9.5:1, like I said it was an extremely low budget build using stuff I already had, not trying to build a drag car or anything. Behind it is a 700r4 with the factory converter and a transgo kit, exhaust system is completely factory until I get money for headers and a catback. It seems to run just fine with the factory chip in place but I was wondering if I should just find a factory L98 prom and call it done or if I should look into a custom burnt prom. With a setup this close to stock would it even be worth it?

Even stock combination can benefit from a custom tune.
