Default Supercharged guys need some help

Well I just got off the phone with my tuner. My car is idling really high (1800rpms). He made one pull and the car made only 7psi and 350whp???? A coupler popped off and once that happened the car idled perfect. I have a fmic on it. With the piping hooked up it idles really high and when piping is disconnected it idles fine. Also I am pretty disappointed at the dyno pull. 350whp.... With all my mods I should be way higher than that. Mods are...

Mmr 4.75 shortblock
Mhs stage 2 heads with cms stage 3 blower cams
Edelbrock intake
Vortech strim with fmic and Anderson power pipe. 3.12 pulley
L/t headers o/r h pipe flows dumped
Upgraded fuel system
And supporting mods

Can anyone help me out and tell me wtf is going on?? Also I got a pretty good oil leak comin from the rear of engine. When it rain it pours

Another thing I forgot, I have a vortech max flow bypass valve. Do you think if I adjust the screw on it it will help with the idle? I've never touched the screw. While at idle barely any air comes out of it. Will adjusting the screw help it open up at idle and maybe fix my idle problem?

What type of MAF setup are you running? And where do you have the MAF located? Also, has your tuner checked your IAC? The rear leak sounds like a rear main seal

i am running a blow-thru maf and its located about 6-12 inches away from throttle body on the straightest pipe. my tuner started to say something about my IAC. went on about unplugging something and the car should die but its not. i can not remember 100% my 11mth old son was screaming and i missed that part. im going to talk with him tomorrow in person. my car made 290whp with stock block/ heads and a stage 1 n/a cam. gaining only 60whp with a built shortblock, stage 2 ported heads, stage 3 blower cams, vortech s trim and edelbrock intake is not right at all....something is definately wrong. but then again he said he was only able to make a partial pull due to coupler popping off

Nah man that dosen't sound right at all. He** I made 386 with just a Vortech V-1 T-Trim, shorty headers, N/A comp cams and a powerpipe. I had a problem with my idling also but thanks to kerns, I realized that the MAF was to far away from the TB. PM Kerns maybe he ca help you out.

Take a picture of your engine bay and text it to (918) 549-0627.

+1 on the engine bay pic

The BOV should be fully open at idle. I am going to go ahead and say that could be your problem along with maybe some other vacuum leaks in other places

Is it open vent or do you have it recirculating into the powerpipe?
