I'm running my new falken rt615k tires. On the blower setup, I could punch it in 1st gear and not break loose at all. On this twin setup, it's laying down big tire marks in 3rd from a nice roll.
I'll try to get ahold of bobby sometime from Cin and use his dyno to see how it reads against the blower on same dyno. The guy I rented dyno from said not be surprised if it's putting down lower numbers than expected.

Put some miles on the z. Seems to be running good. I picked up 6 mph in the 1/8 mile. Haven't put a sticky tire on yet. But has picked up good.
Have a pic of boost graph. It ramps up then drops off a little bit. Doesn't hold steady at 18psi. Still trying to figure that out. I'm running Mac boost controller with vac lines as short as I can get. Have Mac controller mounted to side of Tranny. The vac lines drop straight down to it.

Trying a bigger wastegate would be expensive but MIGHT do the trick, or relocating the external wastegates would likely solve the problem.
What do the hot side manifolds look like? If the wastegates aren't in just the right spot, they'll struggle to hold boost smoothly even if the boost controller is good.
This is assuming you have the controller installed correctly.
What's your wastegate spring pressure? If you want 18psi on the controller you'll probably want about 9-11psi on the spring. Too low of a wg spring can cause boost holding problems too.

Will be interesting to see what happens when you turn up the boost.
