3.5 or 4 BAR?

[THensley]

My new best looks it like I was over 29.5 psi on the log My fuel and spark table go to 31 so I thought I was OK.
My E-Boot Street would have told the true story I just didn't look. I have E-BOOST street 40
So back to the ? 36 psi will give me enough room most likely BUT 43 will I lose resolution on my fuel and spark table ?
This car and tune worked supper at 30 psi log looks good
this also brings my ALKY setup too.Im on E-85 but Ill continue to spray ALKY

400kpa absolute (43psi gauge) is pretty common. It matches up with what a 4 bar map sensor can measure.

To increase resolution you can use map splitting. I will sometimes use 1 ve table for vacuum and a 2nd ve table for boost.
