Default Limit of stock injectors
I was wondering prior to me doing my cam install if I should upgrade the injectors at the same time so I only have to get it tuned once. I plan on doing heads, cam, and stall all at once.

I believe that '98s had the 28lb/hr injectors, and I would think that would be fine for a cam only car.

I think he is right^.
But the injectors may be dirty if they are old.

Mine didn't make it to 400RWHP. I think my duty cycle was at 108% but I haven't checked it sunce I got it retuned. Probably still near 100% though.
