tell me if this sounds normal. when i am at a low rpm (say in 5th gear) and go wide open throttle the car does not pick up smooth. it almost feels like as if i was touching the brakes on and off very light. when i get up in the high rpm's it goes away. dont know if it is a small vacume leak or a missfire or somthing else(dunno) help.
also when you hold your gas down a little and dont let go or push harder should the vac. stay even or go back down?
thanks
 
vac will probably drop a little... since you arent forcing more air through the engine to continue to spool the turbo...

And well your car is "hesitating" Search for the ECU flash.
