Message	Hey Guys, I have a built bottom end 300zx with GT2860RS turbos, pretty much every bolt on you can think of, AEM Infinity 6 Stand alone ECU, running maf-less (IAT/MAP sensor) and for some reason, the car is having an issue making power. We checked compression and it is solid. The car can not make over 400hp. Somethings we noticed: The speed is not reading correctly in the Infinity (Not sure if this is due to running 305/35/18 tires). Map sensor has very erratic readings over 20psi and above boost level. Map sensor is a AEM 3.5 bar and is placed on the plenum on the back left (passenger side). Base Boost pressure is 18-19psi, whic hsi weird as we tested the gates started to open around 12-14psi. All boost leaks were corrected. We tryed tuning with E85 as well, and still could barley make more than 400hp (I am running a flexfuel sensor). I am using 2x Walbro 465 fuel pumps (1 boost activated at 17psi) wired directly using a relay and a full -6AN fuel system with E85 rated hoses, top feed fuel injectors and 1300cc injectors. Any ideas? Some thoughts were maybe the springs/retainers were junk, or my wastegates are junk.
