compressure surge..nahh

are you starving for fuel? i donmt know about the 420s maf and such..but is it fuel cut? what are you tuning with? what does the wb say when this happens

i hope your intake is tight and sitting properly,i hope your airfilter isnt getting its foam sucked into the intake..

is this a problem that just occured? did you change anything before this?

Have you done a boost leak test? Also see if the wastegate and BOV are fine and aren't failing.

well i dont have the intercooler hooked up because i just put the turbo on and wanted to get the car running right with all motor...i had the whole motor redone with everthing new....i dont know alot about fuel cut but it just acts like its not getting fuel in higher rpms could it be the fuel pump???
