Do I need bigger injectors?

Don't you know anyone with data logging software or at least a capable scan tool to check the duty cycle before the dyno? I would definitely agree you want to know if you have a problem or not before you pay for a dyno tune, I thought you were just going to data log your car on the dyno.

That may be a possibility, and a good idea. If I can't find the info from my last dyno tune regaurding the duty cycle, this may be the means to do this. Thanks.

As of right now, it hasn't changed. The large custom cam is not ideal for my setup, but I love the powerband, the feel, and the sound. If I decide I really want to go all out with my setup, this will be the item that would need to be changed. But, with amazingly getting traction at 614 at the wheels with the previous combo, and I can only expect to have a significant loss in traction after the heads have been changed, more power seems irrelevant to me. For those that want to race their dyno numbers, and braging rights around the number it may be good and fine, but thats never been what I am after. I'd rather have power I can use.

Ok, so your keeping the same cam...

I know a certain dyno day that'll help you find out! But I'd just bump the base pressure up to 58 if you need. Or buy injectors to have on hand, and return them if you don't need em.

I saw your dyno day. Assuming everything falls in place, I will have the car tuned in the spring. The whole point of finding out before hand is to avoid the cost and hassle of getting injectors I may not need or pay for additional dyno time. The pressure can only go up so much, but it can be experimented with. Right now, I'm going to try and find someone that can take a look at things before I go with a laptop.

Problem with looking before the dyno though is that you'll be running around, untuned, getting into some power in order to check the DC at boost. Not the way I'd recommend going about it.

Yeah, not ideal, but past finding from the last tune what they were at, I'm not sure there's another way. I guess I could always buy them, and return them if I don't use them.
