He hasn't logged on since slamming the forum for not being nice enough to him.

I know, which is why I PM'd him because that should send him an email notification.

[QUOTE=tomm.brz;3421330]i haven t understood why OP is looking at the value if atmosferic pressure to see the boost..
Atmosferic pression is atmosferic pression and nothing else
Did the tuner say to you he relocated somehow the value of atmosferi presure to show the Manifold Relative Pressure?


when reading on atmospheric pressure I misunderstood it.

I said some people in this community. I did not say the entire forum. the reason why I haven't logged in is because my wife and I had another son so I've been focusing on taking care of my family. I do not go on the internet often either, nice try on the assumption though.

Atmospheric pressure should be 1 bar or 14.7 psi, or it should be less if he lives at altitude, so Reno/Tahoe might be 12.5-13 psi. A turbocharged car will still hit wastegate pressure under load, but it will just take longer at altitude, so his absolute pressure should be the same anywhere. With that said, the delta will be higher, meaning, it will take 1-1.5 more psi of turbo pressure to get to wastegate pressure because there is 1-1.5 less psi of atmospheric pressure. This would lead to more heat and less efficiency.

Hopefully he isn’t confusing atmospheric pressure and absolute pressure. Absolute pressure should be atmospheric pressure + boost pressure, so hopefully he doesn’t look at that larger number and freak out even more, thinking it is solely his boost pressure.

I did confuse the two, what freaked me out was the tuner saying my wastegate spring is too tight and that he set my boost cut to 15psi. My car was tuned in 66ft above sea level. I live 2700ft above. i checked boost solenoid routing and it is routed properly.

thanks for the helpful posts, much appreciated
