High power consumption problem in sleep mode with Atmega328P-MMH 28MI


I have a standard Atmega328P 28 pin which is all going great on 3.3v @ 8MHz and goes into deep sleep of 0.002mA. So I want to put the program into a 28MI size chip. 1) First loaded program and the CPU, ran very slow. Think it is set to standard clock at 1MHz 2) Load bootloader into 28MI 3) Program runs, but sleep is 0.188mA

I think it might have something to do with the hardware in Arduino see below, but I am unsure. Also I have pasted the sleep code FYI

Thanks in advance James
