Max Boost on stock engine with SC
Ok guys, i just got my 650 injectors and im considering a HG from http://www.directtuning.com/store/pc-60874...-C4335-030.aspx Is this what i need to run more than 12lbs of boost? Shouldnt it be 87mm for stock head? Can i use the 89mm with no problems? Should i have it tuned to be right at 12 so i dont need a HG? After tune ill be well over 400 but my redline will be back at 9G

Please explain? If i want to go up in boost to say 14 with my 650 injectors then i thought i had to go to a 3mm.
