Boost spiking
I am having a problem with boost spiking when the second turbo comes on line. I have the boost controller set at 12psi and when the second turbo comes on line the boost spike goes up to 15-16psi. I have a bigger intercooler, downpipe, midpipe, catback, intake, bigger fuel pump street ported engine with 3mm apex seals and a after market computer. If I can't get this boost spiking under control then I'm going to have to convert to twin setup; but I like the sequential better. I have also played around with the pill in the prespool line and I'm still getting the boost spikes. Please help!!!

The problem is that with the midpipe, you are overwelming the wastegate.
