Got my motor built, twin turbo(s480 over stock) dual fueled and 40% injectors. 125lb springs etc etc. having an issue down low with my boost say from stop to anything under 50mph. Now if u roll into the throttle over 50% at them speeds it will build the boost and go, but normal driving it rides with pretty much no boost on either in cab gauge. Vanes sound open the entire time. Done alot of logging, frp stays right on with commanded, vane position stays on with desired etc. so I fogged the block to look for air leaks and came up with nothing. Map stays at a constant number on Efi, like 37 or 39, dnt have it with me at the moment, and baro doesn't move on Efi either. Brand new map sensor installed also when I put the motor back together. Anyone have any ideas what can cause this? It's driveabke but sluggish as hell unless u get into it over 50% tps.
Truck is tuned by rob Coddens. I've sent him some logs and he adjusted on maf table some but still didn't help much. Doesn't have excessive smoke or anything, just doesn't have boost driving around town etc and chargers make no noise what so ever, until over 50% throttle.
