whenever i give the car more than 1/4 throttle on boost it boggles and pops until i ease off the throttle a tad ! any advice on this ? ive tried 3 different map sensors and 2 different missing links! the motor is a stock gsr on 7lbs of boost!

Missing link eh? You're using an FMU then? is it throwing a code. I'm tempted to tell you to get some real EMS but i'll refrain for now.

does it sound like popcorn through the exhaust, when mine starts poppin I know my plug gap is no good and I change plugs w/new gap

It does make a popcorn sound at anything more than 1/4 throttle ! and yes ! i do have the fmu 12:1 and stock gsr ecu, walbro fuel pump and stock injectors and the wastegate is set @ 7.lbs.

All I can suggest is change plugs and gap em at 28-34. I do mine at 32

you are probably run dead lean, you need to hook up an inline fuel pump if you are using a fmu, and make sure the missing link is installed the correct way, its only supposed to go on only one way

Im going to replace my fuel pump within the next day or two ! and new injectors

you could burn down that expensive engine easily... injectors need to go on with the rest of the setup..
