go with copper 1 heat range colder. and if you dont have a tune thats for 4 bar, turn it back down...

I would double check the program and your MAF wiring.

I had the same issue and it turned out to be the wrong MAF on my program. Put the motor into limp mode.

ya i got the setup from a guy that had it running in his car. and the car was reving and idleing fine while up on jackstands untill i took it out on a drive. now it wont even start

so i got some bkr7e's and when i was putting them on i noticed when my little cousin installed the new valve cover he didnt sit the gasket on right so i had a huge vacuum leak. so i fixed it and the car idles fine and reves fine but it wont go into boost.. it drives fine on vacum but once it goes on a load into boost it knocks and starts backfiring and wants to shut off..

idk if its rich, but once it goes into boost itll backfire real back and not continue to drive..

make sure the ecu plug is fully seated then check all of the engine ground points. also make sure the injectoe o-rings are seated and not leaking.
