please help with turbo not getting enough boost

my 93 twin turbo is making 5 pounds of boost when you hammer down from take off. now the funny thing is when the car is going around 40 miles an hour you can be getting 5 pounds of boost let off the gas push back on the gas and it will get 12 pounds and kick you back in the seat. does anyone know what the problem could be????

Your sequential turbo system.. The bane of the FD owner.

upgrade to single turbo

just wanting to fix the problem i dont think the turbo is bad just wondering if anyone had had this problem befor

run them non sequentally (sp?)

hey some of your vacume lines are cracked or disconected so check them all and while your at it zip-tie them at the conection points to prevent this in the future.

yea it could be vaccum lines, I've heard its a common problem on the FD's
