So I have a older AX1600 on my truck, the new motor I built is made for 10-13 lbs of boost but I can only get 3-4 lbs out of the whipple and that is using a 2.75 " pulley, I am leaving alot of HP on the table not having enough boost. I am wondering if I can just get a bigger commpresor ? like a 2.2L

thanks for the help
