I had that problem when I first put my put my turbo in my miata running about 5 to 6 psi. i found out that the timing was off and my wastegate had to be adjusted on the turbo itself and sure enough to care of the problem. oh and I also had to change out the spark plug wires and the coil pack cause sine the timing was off, my wires were arking. Hope this helps.

good info but probably not applicable here. The msp has bad tuning. there is no way around that fact. It is not as noticeable when colder out, but once everything is nice an warm it's a whole different car.

DSM's AFC does a great job adjusting the a/f ratios for little $$$ compared to other piggybacks.

I could not agree more. The first cold night this winter I was like, "so THIS is what this car is supposed to feel like."
