Had my Arrow full race system running about a year now and it runs great. Should I bother/is there anything to gain from an ECU flash/PCV etc?

I'm hoping to add a HM QS at some point

You'll be amazed with how much better It will run with a PCV and custom tune. You'll pickup some hp and it'll just run smoother all the way around.

Are there any 'box' maps to run before it gets a dyno run? (This is for a 2014 636 BTW, I forgot to update my details)

The bike will run better, perform better.... You may not pick up much peak hp but through the midrange you will see/feel a nice increase

And that is better than peak numbers anyhow.

Because the chances of your stock fueling matching the fueling needed for a full system are slim to nil. Even if you think the bike ran "great" it was probably very lean/rich and not good for the engine and could've run much better. Not a big deal to me over a short period of time but over a whole year that is crazy to me. Therefore if I was looking to buy that bike and knew that when you were trying to sell the bike that would greatly impact my decision.

As well you left 9-12hp plus smoother throttle and more linear power on the table, I don't understand why you wouldn't want to get it tuned:O

Get blockoff plates and THEN get a tune.

Like yesterday.

I'd also inspect the valves to see if they are damaged.

Well in that year (just under) I've only managed to do around 700 miles anyway. It's due for service hence the question about mapping etc

were you just trying to save some money? Or were you not aware that a tune/fuel controller was damn near mandatory when installing a full system? Do you have LED light strips on your bike?

Dealer said it didn't need it, it felt fine. My previous bikes I've always had some kind of PC or ECU flash. And no I don't have LED strips

Your stupid sarcasm is awesome, thank you

I got a quote for a PCV and custom remap which was fine but they said because of the closed loop system the PCV can't tune below 5k revs. Are there any alternatives than can tune right from the bottom?

I had a search and read some of threads but can't find a specific answer
