90 pph injectors on a 305...

With a BPW of 65, will this be getting the injector into too small of a pulse width (7747 ECM)?

I have a set of 90 pph injectors here I'm going to use on my 350 but I don't know if they're any good. The only way I have to test them is to try installing them.

No I'm not too concerned about this 305 I have right now

Quick way to get an answer, you might try PMing Pablo. He swapped to carb now I believe, but for a while he was tuning TBI with big injectors and low BPW on a 305. Maybe do a search for his posts, I don't think it was having any idling problems with small pulsewidth.

Try your best to keep it out of asynch. Once I set my switch over point to zero my idle smoothed right out.....But just to test, I'd slap them in there and watch the smoke roll with the stock chip, it won't hurt anything. If you get a good back fire it'll throw flames.....ask me how I know.
