So I have stock internal 4G63, 510 injectors, 2G maf, small 16G (10PSI), stock ECU, strait exhaust turbo back magnaflow muffler, brand new knock sensor, brand new fuel filter, 94oct fuel (with 10% ethanol)
First time actually getting good readings from my new logger not to sure if everything is working OK would like some more experienced people to take a look.

Thanks in advance Corey

Looks like you've got some knock creeping up as the boost rises. Are you on the stock intercooler?

Er... stock ECU with 2g MAF and 510cc is the problem.

The 2g MAF doesn't scale exactly off of the 1G so just putting in 13% bigger injectors won't make it right. You're likely going lean as the airflow rises which is causing knock. Get a chip burned and it should help.

Also double check that your timing is set correctly and then back it off by one or two degrees until you get that chip in.

Reset timing to 3deg bdc instead of the 6 it was at. This is my daily driver so it gets kinda hard to send ECU away and drive it at the same time. no one has a spare kicking around for me to use while I send it away posses a bit of a problem.
