exactly, my compression is low... compared to sea level cars. The 2psi less ambient pressure makes a difference in overall compression numbers. Maybe it isn't huge, but it is still a difference.

I've done some cam testing that shows large gains from just cam swaps. Sure, tuning is still a factor, but there is no reason why a base map for a DET shouldn't work reasonably well for this engine...

I had the standard cams in there for a bit, but changed back to VET cams to see if I could make more power.

VET cams. They are loud all the time, so you don't hear the switchover. The exhaust switchover is wierd though. The engine note just sounds smoother and less harsh, but doesn't get louder.

I know the dyno is not the issue. I know the setup isn't the issue. I tried playing around with timing a little bit on 15psi on the dynojet a few weeks ago, but it didn't seem ...

Ya something is still not right. But with the standard VE cams I still lost power over the VET cams. The VET cams on this setup seems to perform just like the log manifold did before.

Ya, I understand that. The maf voltage is sorta exponential. So I just want to get a sort of idea on where it would be ballpark.

You can already see the voltage isn't linear when 360whp is 4.5V ...

awesome Ashton! That is some serious boost for sure. I have been nervous to really turn the boost up on pump gas up here. I just don't know how safe it is.

I am pretty sure that around 4V on the maf you should be around 300whp. 4.5V should be around 350-375whp. 4.7V is around the 400whp mark?

yikes. Injector duty is way up there then. But I am nowhere near 430whp even... something doesn't add up.

My maf voltage and injector duty both say i should be making a ton of power.
