I have a 2003 Dodge Cummins SO with a 47re. And i had a couple questions. Frist off i have a edge ez and was wondering if i should keep it or sell it and buy like a prdator/puck combo or add the juice to it because i want to get some more power out of it. Next my turbo does like a sh thing right before it shifts in to over drive. it like loeses rpm when overdrive comes so my turbo looses its boost and does like a sh sh noise then takes off again. If i easy in to it, it doesnt make the noise, if i get on it hard it wont, but there in the middle the turbo will do it. and it does it alot to. some people say i need a blow off valve but i dont know and i was wondering id anyone out there knew. Lastly what should a post turbo mounted proymeter read when shes hot. or what sound the egt not reach number wise. thanks for any input
