Built KA24DET compresion a little low?

I know how a boost gauge reads. vacuum should be 20.

My boost gauge (Greddy Profec E-01) reads vac in negative PSI. -11Psi (what I run at) =~-22in Mercury, or ~-75 Kpa.

It would just be 25 kPa, but that is weird that your gauge reads that way, but I guess it makes sense since most people WANT to relate vacuum to pressure, it may just be easier for them to understand.

Werid. ya it shoukd be at -20 at idle.. I know for me tho, when my car is in drive ( auto faggots.. yess... ) when my car idles it is at -17 but when I put it in park and idle, it goes down to -20. Cool huh?!

[PapaSmurf2k3]

Well, I actually wish it would read normally, but it will only display values in 1 unit, so I can either have Vac in PSI, or Boost in inHg or something haha. I'd rather have the negative PSI.

The reason your vacuum is lower in park is b/c the idle valve is opened further in gear to offset the increased engine load to prevent it from dying. In the same way hard turns at slow speeds and turning on your AC will affect your vacuum also.

Were the cams set properly with the cam card included? i know v2/v3 crowers if they are not set properly will cause problems

[WDRacing]

I doubt it's the cams causing a compression shortage. Since the improper alignment would still allow for a good compression number on the compression stroke itself. If the cams were off, depending on what way they are off, that stroke would have less compression. Unless they're both off, but I doubt that.

Changed the cams out and now its reading a little better. pulling pretty decent.

still not quite up to where i think it should be
