u dont need to port teh wastegate dont confuse spiking with creeping its two completely diffrent things.

once u swtich to a DP and MP on the stock sequential system u will SPIKE as high as 17psi if u dont controll boost your engine will pop. u need to take the stock solenoids out of the loop the lines goign to them are wayyy too long.

i run my car with DP and MP at 10 psi with about 1 psi spike and no creep at all instead my boost falls off to more liek 9 psi at redline. if u are interested in the setup i have pm me.

I spike to 15 or so psi with my mid pipe, but when I had a highflow cat I did also. I have a fully open exhaust, my catback is a straight through, I get no boost creep at all.



I think its hit or miss, you either get it or you dont.

if need be mike i can port the wastegate(s) got all that nice motor maker **** at my job, (big ass/powerful) die grinders
