GoldLexus99 Posted July 14, 2009 Share Posted July 14, 2009 hey guys, i was wondering if you guys ever had a problem like mine? or if it was considered a problem/ I drive a 99 GS300, but here is the thing. i am positive it has no turbo nor supercharger...... completely stock. but.. when i drive on WOT, i hear this wastegate/BOV type sound after the car changes gears on WOT. could anyone tell me what this is? it acts as if it had a turbo... could this be my air intake? (stock intake) WOT..... 1rst gear...during change to next gear.. pshhhhh. 2nd gear........ and so fourth.... it's pretty loud. and people have been asking me about it.... o.O please help the noobie! thanks Quote Link to comment Share on other sites More sharing options...
