[QUOTE="BBottoms, post: 456978, member: 1421"] Did a few data logs this afternoon. Rolling into WOT, without a downshift. I did two runs with very similar numbers. Max numbers in 2nd run just before let off were: 2989 rpm 85.9 psi abs EBP (71.2 psi gauge) 52.7 psi Boost 1396 deg EGT ~24.66 ksi FRP (170 mPa) EBP and EGT were still climbing at let off. FRP had no problem maintaining throughout. I don't want to be that guy that says "It's not my truck, it's the dyno" but at the moment I'm leaning that way.... Is there anything that can cause a loss of power while still maintaining data like this? [/QUOTE]
