Is an ECU re-flash needed?

[MSB]

I am putting on a new exhaust, Cattman y-pipe, Nismo catback and Fujita cai on my '07 and was wondering if it would be worth while to go ahead and have the shop Dyno and rf my ecu? I think it would be a good idea to fine tune everything but would like others opinions. Is it worth the $ and what would it really do for me?

Update:Well I guess I don't have to worry about it right now. The shop said they don't have the software to rf my car yet. Will it matter if I wait to rf until I find a shop that can or will it not make any difference to rf with just an exhaust and cai?

you don't need to do that since the ecu adjust the engine's operations by getting signal from various sensors. after a reset it'll do what it does anyways. unless you have trouble codes than it might help.
