I read somewhere that 元1 stock injectors are 19lb/hr, but at 60psi fuel pressure, they flow 22.1lb/hr? What's up with that one? And what would be the correct number for that injector table/how would this effect my truck "haulin tater"? I just had my truck dyno tuned a few weeks ago and my injectors are written in as 19.1lb/hr.If it's supposed to be set at 23.1lb/hr.and I change it to that setting now (from 19 to 23).how would this effect my tune/will I have to get it re-dyno tuned? Thus, that's what he put in the table (19.1). he asked me what the stock injector size was, and I said, "stock is 19lb/hr." I didn't know any different. ![]() I swapped the stock black box for the 0411 PCM, and my local tuner changed a few things. 1996 GMC K1500 350 Vortec (元1).stock injectors are (I believe) 19lb/hr? Why do the stock tunes I've seen (with same engine) have 23.1 in the injector table?
