'98 HX/VTEC-E ECU/Tuning...Will I benefit?

I've got a 98 Civic HX w/ a stock D16Y5 (VTEC-E, 1.6L, SOHC). I've installed a cold air intake, headers, and an exhaust (cat back). These are the only modifications I've made to the engine. Will I see any benefit from using some sort of engine management (such as Hondata)? Moreover, would I see any improvement by taking my car to a dyno and having them tune it? Or would there be no point since I don't have a great engine and have few modifications?

Any input would be greatly appreciated!

I guess that's kind of a relief, since I'm broke and don't have any more money to spend anyway.

I found this post by Marty:

the VTEC-E runs on 12 valves untill 2800rpm then runs on 16 valves on a small cam lobe till vtec at 5500rpm then it is in regular vtec till redline.
non VTEC-E runs on 16 valves through out it's operation and hits a bigger cam lobe at 5500rpm

Is this correct? If so, is there any sort of ecu management I can engage in to make my VTEC-E run like a regular VTEC? None of this 12 valve stuff...

Vtec-e was meant for efficiency.

First off, the 12 valve mode runs until 3100 rpm with light pedal pressure and 2700 or 2800 with heavy petal pressure, which Vtec engages and it runs like that til redline.

You have Vtec-e confused with 3 stage Vtec.
