Boost lag
 

When i hit the gas my car excelerates then lags then excelerates again. I watch my vac.boost gauge and when i hit the gas it starts to pull it out of vac and i get exceleration. Once my gauge reads 1psi the car laggs WAY down untill it reached 5psi then i excelerates.. Is this normal?

do you have an air/fuel ratio guage? you might be running lean at those rpms. what fuel mgmt do you have?

could it be leaks somwhere in the charge-pipes, my brother has a 300tt and it did that, the stock pipes were rubber so he switched to hard pipes and it fixed the problem.
