Night @ the Dyno!

What fuel are were you using?

93 pump gas joe.

[Joe 1320]

Personally, I wouldn't run that boost without using at least 100 octane. The stock heads and pistons are good for N/A on pump gas and over 4 psi without additional octane is just askin' fer it. Stock heads are restrictive and contribute to the higher boost. Better flowing heads and you wouldn't be able to do that so easily. Run it with good gas and my bet is your dip will go away.

ok, im definately going to do that then fast ta. do they sell plug kits for the pcv system? can i use any 3/8th hose from the valve cover to the inlet side of the blower? also, the granatelli mass air sensor is pretty far before the inlet side of the blower it is seperated by about 2 feet of plumbing, the only way to make an evacuation hose fitting would be to fabricate something for the hose on the inlet plumbing to the blower, BUT the mass air sensor is way before where i could fabricate this fitting... the air filter is a cone attached to the filter then the plumbing to the inlet on the blower, would this increase in air effect my air fuel mix since this crankcase pressure is being added after the mass air meter?

thanks,

I would remove the nipple from the intake manifold and screw in a NPT plug. You can get them at just about any hardware/fastener store.

There is so much to type on the subject of going with a MAF or speed density tune using the VE table to manually add the aditional fuel required by your boost signature....so I did a search on ls1tech.com and this is a fairly informative thread. turbolx has a good grasp on the options of tuning.
