Has anyone who installed the EZ notice more engine noise while idling - on the default 3 setting?

This is aside to the ticking noise I asked about before.

Here are my observations -

1) Before EZ installed - engine quiet and smooth (other than the ticking noise below < 50 I asked about earlier)

2) Installed ez on default setting "3" engine just a tad rougher but overall engine noise is louder (btw the power is very nice)

3) Week later I changed the setting to "2" engine still a tad rougher but engine noise is back down to normal (power feels about stock)

I think this is normal but just wanted to hear that others had the same observations.

I should really start driving with the radio on .

 

Well, I never noticed a change after installing the EZ but I have noticed that it seems to make more noise the more miles I put on it. Still very quiet compared to the earlier trucks..
