Blacktop DSM injectors, car runs like ---- on a 450map, runs awesome on a 240cc.
So it runs super super lean on a 450cc map, and even a 390 map, and runs decent (little bit rich) on a 240cc basemap. WTF? The injectors are black tops, and they say "450" on them. Any ideas?

he had a set of bluetops , my old ones, but he wanted to keep the "newer 450s" and now yeah.. yes he has a resistor box, its an obd0 car.
Everywhere ive read it says all dsm injectors are peak and hold. Anyone have evidence to show otherwise?
