Very happy with how linear it is. I don't know what the magic was but it seemed everything helped a little :
DME New Jersey fix
Shark injector
New CCV
DISA rebuild
Verts are a little heavier so not as fast but should be close

William added the vulcan mind meld mod to his car and 'Willed' the 4K dip away.
I hope to get mine installed next week, I'll report back with my own review. I used to have the 4k dip, but was driving around last night and decided to run through the gears and I could not sense it at all in 1st, 2nd, or 3rd at FOT. Not sure where it went :dunno.
Not complaining though.
Thinking about it, I wouldn't say my car has a dip... Seems more like a surge of more power. I definitely feel that it's when the DISA opens. The only thing I haven't done on the list posted above is CCV.
I have the Dinan stage 3 software so who knows if that has something to do with it...
finally took a little video.
the car has the shark injector tune, aFe intake, VANOS rebuild, custom CCV setup.
first and second gear, from 3k RPM:

just second gear pull, from 3k RPM:

dip does not seem present in videos, it is not really consistent, which is odd.

Gawd I miss the sound of the M54B30.
I dont know if this has been answered but Im curious. I have have an obd2 gauge that shows the TPS sensor. In stock from it won't go above 84% floored at anywhere in the RPM range. I just read that in stock form the throttle body doesn't open all the way. Is this true? And if so does the Shark address this?
Im really thinking about a tune. My power is utter garbage. Its very spotty. I even noticed the car is slower if I put the pedal to the floor all the way compared to when I floor it and lift of the pedal a little to about 80% the car accelerates faster. God, this just reminds me of how much I hate electronic throttles. Its more of a suggestions that an actual action. Makes me miss my e30.
The sprint booster or pedal box will address the throttle lag due to the electronic throttle. They don't address performance. A tune will address performance (minor improvement, but improvements none the less). A tune will not address throttle lag.
