Low Boost When Shifting

[k3k0a]

ok i got a problem, my car does not boost over 7psi after shifting, for example i can downshift/launch and the first gear will shoot straight up to 14psi and stay there but right when i shift, the next gear only hits 7psi and holds there till 5k and it creeps up with the rpm's and holds at 14psi, same thing on the freeway i can down it to any gear and the same thing happens.... i dunno whats wrong, im thinking it might be the new joe p mbc. but i really dont know cuz after i put it in, ive only made 3rd gear pulls to tune it..... tnx in advance

 

[uh-oh]

how do you have the boost controller hooked up??

i hooked it up the way the instructions told me to, the fitting straight in line with the adjustment knob goes to the tap between the bov and the intake manifold, and the fitting thats off to the side is going to the wastegate

Are you sure you arnt leaking boost somewhere have you tried a intake leak tester?

i just did the leak tester today, and i found a nice size leak on my uicp, i fixed it and i thought that would fix it but it still didnt, it made it a little better though... and i tried the leak test after and there were no more leaks, only thing was i was using a bike pump..... does anyone know if i NEED to use a compressor?
