Yea its crazy maybe it was joint design between the two
Question about the QTP Cutout. Does it improve performance in any way? And I guess it allows you to keep the stock exhaust but get a little more sound from the engine right?

It gives me power, look at my vid of the dyno you'll hear when Scott opens the cutout and it produces more power, cuz it allows the turbo to spool up quicker that's when it made 346 hp and 353 tq.

When you take it to the track, run it with the cutout closed until it shifts into 5th, then open the cutout for the power jump since you will not be shifting to 6th.... may help just a bit

There is a distinct difference in tuning needed between open and closed. He has been instructed to run it only closed until we can get a handle on the inability of the ECU to shift the car on time. Running it open will lean out teh car too much. We did not want to tune it on cutout open and have it be slower on cutout closed because of a rich situation so after it was tuned in 4th, we closed the cutout and retuned it for 1320' on a closed cutout.

I used a QTP downpipe in my old Subaru wagon, and had it tuned for running with the cutout open, and just ran a bit rich at WOT with it closed... different situation since I didn't have problems shifting either way I just ran with it open at the track, and it didn't really matter for daily driving where I was closed loop 95% of the time.
Another option for shifting with the cutout open.... put it into sport mode, and manual shift it, and treat it like a true manual by lifting off the throttle when you pull the paddle to upshift. Reducing the torque load should allow it to shift, and then you go back to WOT. I used to do this just for fun in my MR... makes the car sound like a true manual going through the gears instead of it sounding like an automatic. If you practice at this, the shift should be almost as quick as leaving it in drive
