boost problem!!!!!

[azkcar135]

my brother bought an 86 daytona that has been turned into an tII by the looks of it it was a wiring hack, but it was done pretty good. my problem is that it still has the the tI turbo, and the it seems like it takes the turbo too long to spool up like 4000 rpm it hits 7 psi, them goes to 14. i also noticed that the wastegate can has two orfices a big one and small one what do i do to get it spooling at normal rpm amd where do i hook up the boost controller? help me please!!!!
