98dropta

iTrader: (10)

just got done installing a cam in the ride and after i installed it the car runs great on a stock tune...........i had it tuned and now when i rev it up the rpms drop and it almost quits and then recovers and idles steady at 1000 rpm....could this be a vacuum leak?
where should i look for it?

the cam is a TR230
on my 98 T/A M6

thanks
