Okay I was at the dyno Saturday morning im running uberdata for now and i have 1000cc injectors we got it idleing good anf then slapped it on the dyno so were doing the runs and everything goes good just a planned wastegate has 9 pound spring in it so i reads 8 on the gauge it makes 257whp6500 and 233ft lbs.at 4300now that for a good hour. so then it all happend when we went to crank the boost to 10psi then it will bog every now and then. when you go to give it gas then also at 4000 it does it to 6ish.timing its good and fuel curves are all good so we change the plugs and it still does it what else sound i check.. Im gonna check out cap, rotor and wires .also install my msd digital 6 and msd coil.If some may point me in the right direction.
