So i installed my 2.5" eurosports turbo back today and i notice that when i really get into it, the turbo spool is intermittent..its not a solid "shhhhhhhhhhhhhhhhhhh". It seems to be more of a " shhhhHHHh..shhhhhhHHH...ShhhhhHHh" with almost mini pauses. Does my ECU need time to adjust to the new exhaust? Is this a result of the ecu not knowing the proper air/fuel ratio? Am i completely off?

Any help with this is greatly appreciated.
