, i just installed the buschur uicp kit today and the mini battery kit, before boost was spiking 22 psi or so holding at 20-21 now it is spiking at 22 still, but dropping to 17 or so when i first put the pipe on it blew off the tb, but i re tightened it real well and nothing has come off since just seems odd how the boost is dropping so much with this change

 

fixed

 

What did you do to fix it, because I think i'm having a similar issue.

 

likewise.. wud love to know what was wrong!

Thanks!

 

i believe it was just a loose coupling then i reset my ecu, and it was very humid the initial day intested it i was only peaking 17 psi, not it is fine holding 22 or so i had also noticed dealership must have messed with my mbc after 30k maintence there were marks where it was supposed to be, and it was 1/4 turn back from where it was supposed to be, but just check all your couplings make sure they are tight and reset your ecu aka disconnect battery if you don't already have your small battery installed
