Running Rich after 16G install

[97moneyhole]

Just yesterday i change from a 14b to a s16g and reinstalled my front mount ic. Now it idles normal but when i throttle over 50%(start building boost) my A/F guage drops down to 10:1(rich). I disconnected my safc to see if that helped (nope). I believe i have a boost leak but i wanted a second oppinion before i tear it all down agian.

oh yeah forgot to say that it idles at 15-16vac and will boost to 12psi (bc set at 12psi) in second gear before falling on its face.

Yeppers, if your boostin and it starts to stumble that bad I'd start checking for leaks. What shape is that FMIC in? If you just reworked all the plumbing and the problem has just arisen, then it sound's like a leak.

fmic is in perfect shape. thanks for the response.

No job, which involves the intake tract, is considered complete until a boost leak test is performed, it would be like calling a clutch job complete without bleeding the hydraulic system.

BLT for the win, your MAFS is before the turbo and it seeing more air then the engine is ingesting, so your MAFS is calling for a bunch fuel but not getting the air. If you didn't get this problem prior to the 16g install, double check all of your hoses and couplers and try the BLT.
