Will I Need To Know My Flow #s For A Mail Order

Sorry if this is posted in the wrong place, but will I need to know my flow #s on my heads to get a mail order tune? I bought these used and don't have any #s and the guy that I got them from can't remember either.

Can I get a tune close to drive the car for a while and then get the car dyno tuned when I have the cash?

Thanks in advance

Its one of the things asked. I would talk to your mail-order tuner and see what they say.

I'm planning on a madz28 tune, I'll have to send him an email. I'm hoping to get a decent mail order tune and then have it dynoed later this summer to get all that I can out of it and the sheet LOL
