I just did the ETTC mod . It seems that when I have the switch hooked up I only get 13psi of boost in both sequential and true twin turbo mode. When i disconnect the switch I get 17psi which is normal cause of the VSV Mod. The car pulls fine when i disconnect the switch. The car has 76,000 miles on it with the original turbos and I'm at BPU. Could it be a boost leak, but if that was the case then it wouldn't boost right. I 'm stumped. Any help would be much appreciated. Thanks
