how much did the boost level change with the new header
which is very weird considering i went from cat to test pipe and better blowing header. it was 50 degrees out though.
i will be able to tell better when its 70ish degrees out.

The last info I had before the header was 11 psi in 60deg weather.
And was doing 332 @ 8psi in 70 deg weather. (135mm pulley dynodynamics)
SO taking the last dyno run that puts the Ve of the setup at 1.0968 with the 135mm pulley and the exhaust before this mod.
So before this latest modification with the 150mm
383.11hp @11psi in 60deg weather Ve=1.09680 same as before because this is still calculated with the original header
After this latest modification with the 150mm crank pulley
393.07 hp @10.7 psi in 50deg weather Ve=1.11687 ve being a little bit better because despite being colder which should increase the psi; the psi when down because of a better flowing exhaust system.
This increase in efficiency is also backed up because it was necessary to add fuel.
-----------------------------------------
393whp come on only 7 more hp to break 400 Camuman/Mase prove me wrong on these numbers and please hit 400whp.
