Dual fuel system either gas or propane

ok i got the truck to run really good on propane .... im still having problems with wot surging in gas mode.. almost feels like a maf issue... anytime I make changes to the maf it bucks and dies LOL.... im still very new at this any help would be great ... this is my current config

[trunks604]

all fixed ... stupid injectors were not 39# they are actually 39.5# prochargers instructions were wrong

[etm351]

yeah all kit manufactures don't list what it is you have to look at the # on the injector whipple has got me a few times with that

[trunks604]

yeah this one got me very puzzled for over a month....

[etm351]

just curious what kind of power did that setup end up making and how much boost ?
