Assume *everything is fine* I usually get these readings. "Base tune" done with dsmlink for 750cc injectors.
1. At Idle, with a stock head, what vacuum should my gauge be reading? I'm seeing 14-15 in/hg with .25g/rev as per link.
2. At idle, link reads 5-8* timing, constantly varying, is that normal or should it hold 5* all the time? Reading .25g/rev or 31hz per link.
3. E3B16G, stock head and bottom end and base tune in link, rev launch set to 5500RPM, what boost should I expect to build? I'm seeing no more then 6-7Psi.
4. At what RPM should an E3B16G reach say 23psi of boost?
Assuming I now have a problem (Just came back from a weekend warrior cruise).
5. At idle, CombinedFT is now off +10%, boost leak?
6. At idle, Low g/rev (0.19) = confirms boost leak?
7. I still manage to boost 23PSI but at around 5000RPM, my G/rev goes from 2.9 and dips right to 2.2 and falls off to 2.0 by 7000rpm, what causes this? Let me guess, boost leak? But I still hold target boost....
Did I jump a timing tooth???
Thanks BroDSMers.
*EDIT* more Questions
8. If I have an E3B16G, does that automatically mean I have an E3 02 Housing? Ordering a gasket, need to know please.
