and I would bet both legs and both arms it was timing and load, was the 50psi corrected IE minus 14.9 or not, either way 50psi in the grand scheme of diesel combustion pressures matter not a jot what

Lets say with the aggressive tune I managed to blow the head gasket at 50 PSI but I'm pretty sure it was the drive pressure that got it. I would suggest 40 to 45 PSI as a limit.
Well I pulled a small hill yesterday using a tune I wrote that brings the CAN BUS in pretty quickly on the Quad Adrenaline. This combined with Mach 4's (Flux 150 inj) think his 2700 ml/min is similar to most 7x.010's and saw 38 just barely rolling into the go pedal. I am guessing 38-40 lbs of boost would be the max for head gasket longevity? One surprise was that my EGT's are really reasonable at 900-1100. Seems like it starts barely slower vs RV275s like maybe one second on the key. Idles great. Also everyone talks about the sac nozzles being louder at idle but mine is slightly quieter.
Thanks
