Default Just recorded some logs. Do these results seem right?>>

<center><img src="http://pictureposter.audiworld.com/101112/slide1.jpg"></center><p>Settings:Revo std (boost 6 timing 3)on 225 with BM 5.25 &amp; 1.5. I know its high and is not ideal but...the results are: Command press goes to about 2350mbar at 3000rpm then tapers of gradually seems ok. tapers off almost in line with command BUT manifld press hits commmand then tapers off much more from 3600rpm&gt; see graph in pic. NO CEL or DTC's. Is this right or do we have a leak?
Other Mods: samco hoses, evoshield matched spacer,Forge DVR (green spring),TTDA,****, Blueflame catback.
By the way the hiccups are still there
thanks, Dirk

Default Aha, that may explain it. boost gauge says peak 24psi, hold about 19-20psi.>>

then taper off to 17psi. BTW MAF signal shows 181 g/sec max, but not all the time. Did 5 runs back to back without much heat soak. MAF hits max of 177 to 181 typically at 6200 rpm.How come th graphs on you Fotki lie much closer together though Steve? thanks. NTW I have not done a leak test yet coz i still need to buy a compressor.
