Question regarding cam marketing I noticed that several of Thunder Racing's camshaft descriptions explicitly state that either no tuning is required, or tuning is required "only on automatic transmission models."
Just curious how true this statement really is. Take, for instance, their custom "old man" camshaft. It's a 214/220 .600/.523 115 LSA. Their dyno chart shows it picking up 30RWHP on a car that already had LTs, ORY, exhaust cutout, and airbox lid. This particular cam description clearly states, "no computer tuning required."
So basically, if I were to install this cam without tuning, there would be no worries of check engine lights, air/fuel ratios being all over the place, etc. etc.?? The "no computer tuning required" blurb really got my attention.

Not that would be worth anything...going to a bigger cam usually means you lose a little on the low end (like where you would normally cruise in your car). But, the nice thing is that you really gain that back and much more from 3k RPMs on, and usually up to 6.4k-7k RPMs. Your stock rev limiter is 6200. Only a tune can change that. So really, you'd be giving up some down low, getting some of it back, but leaving a lot on the table since you would still be limited to the stock rev limiter.
Maybe not the best example, but IMO, every single mod that affects airflow into and out of the engine can benefit from a tune. And IMO it should be done.

I think it is just a matter of can you run it without a tune safetly? I would say yes. Are you leaving power on the table? probably 5-10rwhp on a small cam. Would you benefit from a tune? Yes even a stock car can benefit from a tune.

Will you benefit from tuning??? Yes. Is it necessary with that cam??? No. The point is that your car will run ok (and shouldn't throw an SES) just by putting that particular cam in. I did it in my truck and it worked fine. Much later I did spend time tuning my truck and it is better, but it was still quite livable on a stock tune. With some of the larger cams out there you would be lucky if the car even runs without some tuning.
