Evil smasher/ KSS glitch help

I usually get the infinity to about 140 even then sometimes pyro Pete will kick my arse ?

 

That could have to do with the element of the infinity not being effective against pyro Pete

 

Try using the glitch with a sand hawk, then go for pyro pete

 

no i always use the same weapon on pyro pete usually 140 i have no probs then just lately i had to increase cause he was kicking my arse thats why i wondered if he had a damage increase ?

 

I solo'd him a few times recently with my infinity around 200 and had 0 problems taking him down
