Anyone any success in fixing hesitation

[spoolboy]

I got it. Sometimes worse than others. I noticed it from the day I picked it up but thought it would go away after break in was over. I was wrong

I have it too...

Since I picked it up, it Has been hesitating, gasping for air at around 3500-4000 rpm.. I drives me nuts (bang)

AGR#7 and others have gone to a cone filter and associated tubing and seem to have said that it eliminates the hesitation/hiccup/whatever you want to call it.
[/b]Guys and gals who have done this mod[/b]: Have you ever experience the hesitation afterwards?

Check the poll (other thread). Vote there, and write Mazda. Politely.

To me it really sounds like a turbo breathing problem (like it has asthma)

The turbo has some type of turbulence and then when enough air velocity is going thru, the air stabilizes and smooths out making that "vtech" feel..

This is my opinion only, but it kinda feels like the turbo is choking somewhat and causing the surge and stumble in the engines

We have dual stage intake manifolds like gsr's. Has anyone thought of that
