No codes. Stock MAF and using the TMAP that comes with the supercharger.
Is there any chance that the butterfly inside the S/C was gapped incorrectly before the installation or has gone out of adjustment (loose locknut) since the install?.

Yes because I replaced the old faulty bypass actuator with a new one before I installed it. I followed the how to the best I could, but since I've never done one before I may have done it wrong. I adjusted it until the feeler gauge felt just right to me. Do you thing it's too open or too closed?

Your guess is as good as mine. I just recall the installation instructions being quite explicit about itís accurate setting.
Perhaps your tuner, or someone more experienced here can chime in.

Send CSG an idle log, and let's see what Zach can do.

The review of the log is free; if he thinks it can be made to run proper, then he'll let you know to purchase a tune.

Iím interested in this as well. I donít have the problem to the extent described, but I do get some occasional idle bounce. It seems to happen only after the car has been run for a while, is turned off, then started again shortly after while still warm.

that happens often and it s mostly because even during a Warm startup, the ecu apply its hardcoded cold start strategy for a little time, so you have the 2 injections at 50/50 and they are hardly well scaled to each other specially at that low opening time for them
So that creates the instability in rpm and afr

With stock tune it s less noticeable because idle rpm after startup are usually higher than when tuned aftermarket
you can ignore it if it doesnt cause any relevant problem to your drive

Thatís good to hear. If Toyotaís ecu is anything like Honda, the idle ďlearnsĒ over time as well. Yesterday I drove all over the place with multiple hot and cold starts and didnít have any bounce.

Hi, has anyone replaced the Edelbrock coolant reservoir from V2 version to the latest "universal" one?

https://superchargersonline.com/prod...ler-reservoir/

My V2 has been leaking and they said to replace it with above one. But design/size is quite different so need to figure out the brackets/tubes myself. Hoping someone already has experience with this.

Is the tank itself that's leaking, or the cap ?
I seem to recall a leaking cap being mentioned by others. A quick search of this thread might help.

If the issue has been there since day 1 of the install and you did everything else correctly, it may be your intake manifold gaskets under the SC. I will tell you, it is VERY easy to severly damage these gaskets under the weight of the SC and have no idea what you did (ask me how I know). They fall out under gravity when lowering the SC down, they get pulled out of their grooves when shifting the supercharger around to align it, they get cut by the sharp, unbroken edges of the machined groove. Worst of all, they are uninspectable after you bolt the SC down. You might still take a look and see if you can see anything around the runner base. My first set of gaskets had to be scrapped for the reasons above. Thankfully I found it by mistake before first start up because I had to remove the SC for other reasons or I would have been chasing a problem for a long, frustrating time.

Can you replace the gaskets by undoing the bolts, lifting the SC up with a few people, and sliding new gaskets underneath?

I really don't want to disconnect the whole assembly...

I was able to lift the S/Cís left side about an inch when I needed access to the clutch slave cylinder banjo bolt. I donít recall which, if any components I removed to free it up.
I believe I simply removed the six bolts, slid a pry bar between the left side runners, lifted the unit and placed a 1 1/8Ē wood dowl between to support it.
After repairing the slave connection leak I was able to reach my fingers under the manifold to confirm the gasket was correctly in place before dropping the unit back into the heads. A successful solo repair.

Awesome, thank you so much!

I think it may just be the intake, ECU bracket, and injectors I would need to remove before the 6 bolts.

I haven't confirmed or felt the vacuum leak there yet but I rechecked all my hoses and couldn't feel anything leaking... So I'm considering just replacing the gaskets hoping that was the issue.

Might be worth checking SOCON's post #4529 on page 324 for a cool way to lift the blower
