looks like i had T'd into the line for the Trans modulator which also T's into the primary vacumuum block when i did my first test.
tested direct without the T and now showing 5psi and climbing to 6psi at the top of the RPMs.

ill also see if i get any more boost with the BCS bottom vac line off ...

i also used a vac/ 30 psi mechanical pressure gauge. i then added another pressure gauge to confirm my first gauge was proper. pulled vac with hand held tester on test rig to confirm no leaks.
ill post again after running without the evap canister line.

instead T ing into the Fuel Pressure Regulator sense line as shown in the links, i T'd into the next one up on the vac tree which is the Evap charcoal canister.
Boost control actutator tested on the bench before install and after intall solenoid was tested as per links and all looks proper
all ...

thats what i thought for the tap. i was seeing 2psi max at WOT. i thought that was really low. did come out of vacuum quick but i had expected around 7psi. i dont know what the M62 can put out. (vac was good at idle,18-20 in.hg)

How much boost does a stock M62 Gen III make?
Is is ok to T off of the Charcoal canister line to measure?

Currently looking into tuning software to record the data and send it to a chip burner.
Got to fix the exhaust cracks first
Andrew

repairing and reinstalling the Gen2 blower is always a good option still need to fix the exhaust manifolds regardless. thanks for your honestly. i still like power, even if its a 4 door family car.

thanks for the tuning/ manifold link. i reset the PCM, still running rich. ive got 43psi Fuel Pressure with key on engine off. and 48psi, running, with vac line off of regulator. (open port covered). ill get another set of manifolds and repair and go from there.
Looking into chip reprogram but can ...

got the car on the scan tool today. no knock, extreamly rich though...950 on the O2s 150 on the BLM
think i will check boost, fuel pressures next and repair the header leak.
also showing Quad Driver 1 = BAD not sure what that means but it was not "OK"

not sure what the TPS is suppose to be set at ...

willwren.....replacing the EGR seal? yep should be no problem since you told me how to .
J Wikoff....good idea for the FPR will it fit into the fuel rail properly? i have the stock 92 series I in now.

i put the new reman Delco MAF in yesterday. it idles much better than the 92 MAF but boggs down ...

ok thanks, glad i asked.

I got the topside of a 95 SC Riviera for 125$, intake manifold, SC ,throttle body, injectors, fuelrail, and FP regulator. unfortunately the MAF was gone already. looks like the SC was already rebuilt as it had a company rebuild tag on it. i do have a scan tool but the ALDL port is right above the ...

Which company makes a good replacement MAF ? Cardone, Standard,... are GMs still available?

did you find any difference in the EGR pipe to Blower? On the Gen 2 the EGR pipe hole is 1/2 in and the Gen 3 it is 5/8in. i used a gasket and some washers to get it to seal but will probably burn out sometime soon. What did you do if you found the same difference in the SSE?
Whats a mini AFC? where ...

i found a good deal on a decent Gen 3 M62. so i went and swapped out the leaking Gen 2 in my Park Ave Ultra. It wasnt till i went to change the maf screens that i realized that the Throttle bodies were different sizes as is the EGR.
i was able to get it to run. im in the process of getting the ...
