Looking for professional tuner advice...
 

Throwing this here even though it's already in engine/exhaust because I'm not sure which is better.
I'm currently running a great UEL header, 2.5 OP, motiv HFC FP, invidia q300, and OFT stage 2 UEL tune.
I'm considering trading up to an Ace header (250 or CS400) and getting an (ecutek) dyno tune.
Is there really much power to gain with this swap? What about area under the curve?

Also planning on upgrading to a JRSC after a whopping 72,000 miles, would I be realistically much better off with an EL header for this rotrex system... or is the difference negligible?
Thanks,
David

Dyno tune not worth it for NA if you're not going to spend several sessions dialing it in. Wait until you get the SC.
