My previous engine was much weaker than most down-low.

My car felt sluggish before engine change (quarter-mile time of 18+ sec proved it). It still felt sluggish after engine replacement. It was brand new engine from Japan too. Then I still felt car was unresponsive and dealer changed catalytic converter and computer but still not much improvement. Then I got new spark plugs, battery and new starter and now car feels strong again! I can feel me getting pushed to the seat when I accelerate unlike before (where I couldn't feel if car was moving or not... heh). XD
So it must be, you have to have
1. new engine
2. new catalytic converter
3. new computer
4. new spark plugs
5. new starter
6. new battery
for the car to restore its power (in any order)

1. I'm on the 'new' engine...I hope I don't need ANOTHER.
2. I'm on a new-ish cat...although before the old engine was replaced I could feel the car losing power. I BEGGED them to replace the cat along w/ the new engine. They refused.
3. I'm on the newest flash, iirc - unless there's been a NEWER flash out.
4. Had new plugs on the old engine
5. Have the upgraded starter
6. have the upgraded/new battery.
I'm hoping it's the cat...mostly so I can rub it in a bit.

I can't find the link to where I read that but it makes sense to me. Maybe you will just have to blindly trust my words.

The previous engine had the 'after freeway cruising = no Power' mod...so I think it was ready to be replaced - but I kept telling them I could 'smell' the cat, AND the car was pulling 'weaker' up top...getting worse. He told me the smell was from "'sulphur' they 'put in the gas, during the winter."
Right.

I might ask the mazda dealer to spot me $80 to go back!
Problem is - that exact dyno will be removed monday or tuesday at that shop.
They're installing an AWD dyno.

But what I do is I barely rev the engine when engine is cold but when it reaches normal driving temperature... I REV!!!!

just wondering, because that would be a big difference.

I find it interesting that you refute this. What am I missing?

After Eight days Mazda told the dealer they will not fix/replace anything. "Everything about this engine tested 'normal'" is their excuse. :-/
I have an appointment to speak with a district guy, but I'm not holding my breath for anything good to come of this.

Mazda sucks! My regional rep has not returned my call so I hope you have better luck.
If you do have the HP dyno in hand and the HP of the car is stated in the manual. You have proof the car is not meeting specifications. You have a leg to stand on here.
Worst case senior is you pay to have the work done then recoup the cost in court. Just make sure you have a provable case.

Sounds like BS to me.....there is no way that dyno graph was normal...
If it was me...I'd pull the cat and put in a midpipe to test and see if it runs better. Maybe even a dyno. Did they pull the CAT and visually inspect it?? The stupid thing can be plugged and still get normal feedback if the front brick is OK.
