I have a 97 gsx with a stock t25 and just recently I have been having some problems. I notice that when Im driving on the freeway and my rpm's are between 2k to 3k, the rpms drop really quickly then go back up. When it drops my car shakes a little bit then stops. It does this even when I keep the gas pedal at one certain speed. Im not sure what the problem is but it just started happening. I think it might be my intake because I don't have my greddy BOV rerouted back to the intake tube. But I have no idea....Also I dont know why my car begins to shake once I reach 100 mph. Any feed back would help. Thanks.

recirc the BOV.... Unless you are using a way to meter airflow after the BOV you have to recirc. It is very possible that when cruising you are pulling enough vacume to open the BOV and loose all aircount.
