fuel cut at 5psi?

[jerseydsm]

ok my stock turbo blew so I got a small 16g. In first gear i dont get into boost until 5500rpm and in second when i hit boost i have serious fuel cut at 5psi(around 5000rpm). The same happens in 3rd and 4th. Whats the deal?

You need to check for boost leaks. You should be hitting boost much faster in 1st than 5500 rpms.

Large boost leak somewhere in your system. Do a boost leak test and I bet you find a huge leak!!
