Boost Problems.
 
Well I went to get dynoed yesterday, and I am not very happy with the results:
Max Power = 341.9
Max Torque = 347.1

But while doing the testing I was in the car doing the adjustments on the S-AFC and the boost controller (Blitz SBC-iD). We got the AFC to adjust very well, but the boost controller would not cheange the boost AT ALL!! I started out with my set=50, gain=10...max boost=12.6----second run, upped the set=65, gain=13...max boost=12.9-----third run, upped the set=75, gain=15...max boost=12.9-----fourth run, upped the set=86, gain=15...max boost=12.9-----fifth run, upped the set=100, gain=15...max boost=12.9 then we quit. I did notice that the boost would peak then start to decline even though the rpm were still climbing. Do you think I could have a boost leak somewhere? Need some help here! Thanks!!
