Flipside currently has plans for extending the runners out and upwards to add about 4" of length to them. I won't be part of that development because I'm selling it as soon as I get it back, but perhaps the next owner will contact Rob and work with him to finish this project.

It took me 1.5# more boost with the 99 intake manifold to equal the Flipside manifold using the same timing map. That difference will just get bigger as more air is pushed through it. I also didn't play around with the timing at all. Any areas over 7000 rpm don't have any timing in them (knock sensor set too sensitive and it pulled timing) and that's the reason it falls off severely there. These runs were purely to get a comparison.
It took a little work to get this to scale, but you can see, the only place the aftermarket did you any good at all was on the low end - sub 4500 rpm. Maybe I need to take a better look at it, but it doesn't seem from what you've shown you're really getting a LOT out of it. Maybe a bit, but not a lot.
For that matter, didn't you do this with VICS locked in one position? That would hurt it's low end, and you'd expect the big jump around 5k.

I think there's bit of confusion here. On plot #125 ~ it is showing that with how my car sits NOW, it took 1.5# more boost to equal what I got from the Flipside manifold. I've made improvements to the car since I pulled the Flipside manifold off so it's not a fair comparison. Sort of like how many people say "I don't need that part, I'll just turn the boost up". If I put the Flipside manifold back on, I could put down even better numbers than I did last time. Which really bothers me because when I get the manifold back I'm going to sell it.
Here's the closest apples to apples comparison between a stock manifold and the Flipside manifold on my car. It's not back to back testing, but it's all I have.

I've changed from an open dump tube to recirculating, aftermarket exhaust cam with a different, but stock vvt cam and a few other small things. As for the VICS, it's locked in the open position.

After an alignment and adding FM front and rear sways I'm very happy with how the car feels. Running the front bar on full stiff and the rear on full soft seems to be working great with my suspension and driving style. Pushed it quite hard yesterday and it felt solid without excessive oversteer.

Currently the MTs are mounted on 8" 6ULs but sitting on a shelf in the garage and the car is on RS2s all the way around on 8" 6ULs.
For now I have it at at zero, but I'm not running a factory exhaust cam and when I do play with it I'll have the car on a dyno.
I've actually been trying to shed some power this year to make the car more drivable on street tires. I put a smaller wastegate spring in and now am running it at a max of 16# of boost and my timing is several degrees prior to mbt.
