I compaired mine and your video, seems were the same acceleration wise to about 90, then I start slowing down. aerodynamics maybe? Or possibly my stock crap cooling system getting hot causeing a reduction in timing. Cool video!

so how are you getting around the 11psi fuel cut? The exhaust sounds loud for having just a FM dp and stock exhaust.....

I have the boost cut resistor modification to bypass the boost cut but I think my boost sensor went bad because I took the boost cut resistor mod off the boost sensor & still do not get the boost cut anymore.

As far as the exhaust goes I disconnected the muffler from the mid pipe & put in a temporary turn down pipe for the fun of it. I also removed the large rubber boot that covers the shift lever hole so noise comes up from the engine through the hole more. I bought a test pipe a while back for my 93 miata that fits where the cat converter is but i modified it to fit where the muffler connects to the midpipe on my mazdaspeed mx5 & every once in a while I put it on my mazdaspeed mx5. It is loud.

I also have the throttle position sensor disconnected.

The stock ECU causes the engine to run lean until the computer goes into open loop mode around 5000 rpm's . Disconnecting the TPS makes the engine run rich & gets rid of the lean spot.

Tell me more about the TPS disconnect, and how runinng 14psi on that setup is safe. If it's an alright thing to do for the long-run, I may consider it.

Fix your WOT hesitation (TPS signal limit)

Is your temperature gauge broken or something? Or do you always beat on the car when it's cold?

For some reason that doesn't seem like a safe idea, as far as the TPS goes.

I did a stock temperature gauge linearization modification.

So you do beat on it when it's cold? I don't see why. That's a good way to seize a piston and cause excess wear.

my temp mod is slightly different in linerization from the one in the picture above. All these video's were taken after driving on the highway many miles pulling over for for a minute then taking off or driving on the highway many miles slowing down then taking off. The car is up to opperating temp in all the video's.
